Answer:
52
Step-by-step explanation:
We can write this out as an equation. Let's say that the teacher's age is x. Triple the teachers age plus the students age is 163, which can be written out as:
[tex]3x + 7 = 163[/tex]
We want to isolate the variable, so subtract 7 from both sides. This gives us:
[tex]3x = 156[/tex]
Finally, we divide both sides by 3, giving:
[tex]x=52[/tex]
So the teacher is 52 years old.
Hope this helps!
Answer: The teacher is 52.
Equation: 7+3t=163

A rectangular frame measures 2 feet by 4 feet. How much money will I need to make this frame if wood is $6.00 a yard?
You will need 16 dollars
Step-by-step explanation:
Since there are 3 feet in a yard divide the 6 by three that will be 2 dollars per foot. Then 2×4 equals 8. Take the 8 and multiply it by 2 then you will get the total of 16 dollars
What is (6x+4) - (4x+2)
Answer:
x = -1
Step-by-step explanation:
1. Simplifying
6x + 4 = 4x + 2
2. Reorder the terms
4 + 6x = 4x + 2 to 4 + 6x = 2 + 4x
3. Solving
4 + 6x = 2 + 4x
4. Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right. Then add '-4x' to each side of the equation.
4 + 6x + -4x = 2 + 4x + -4x
5. Combine like terms: 6x + -4x = 2x
4 + 2x = 2 + 4x + -4x
6. Combine like terms: 4x + -4x = 0
4 + 2x = 2 + 0
4 + 2x = 2
7. Add '-4' to each side of the equation.
4 + -4 + 2x = 2 + -4
8. Combine like terms: 4 + -4 = 0
0 + 2x = 2 + -4
2x = 2 + -4
9. Combine like terms: 2 + -4 = -2
2x = -2
10. Divide each side by '2'.
x = -1
11. Simplifying
x = -1

7x + 4(-3x + 6) = -7x + 38
Answer:
x = 7
Step-by-step explanation:
Given
7x + 4(- 3x + 6) = - 7x + 38 ← distribute and simplify left side
7x - 12x + 24 = - 7x + 38
- 5x + 24 = - 7x + 38 ( add 7x to both sides )
2x + 24 = 38 ( subtract 24 from both sides )
2x = 14 ( divide both sides by 2 )
x = 7

Step-by-step explanation:
3x(x)+3x(8) + 7(x)+7(8)
3x^2+24x+7x+56=
56+31x+3x²
Answer:
3x^2+31x+56
Step-by-step explanation:
First, we need to multiply using the FOIL (first, outer, inner, last) method.
Let's multiply the first terms together:
3x(x)=3x^2
Now we multiply the outer terms:
3x(8)=24x
Next we multiply the inner terms:
7(x)=7x
Finally, we need to multiply the last terms:
7(8)=56
Now we have this:
3x^2+7x+24x+56
Combine like terms:
3x^2+31x+56

The ratio of males to females in a cycling club is 5:3.
1/3 of the males are under 18
2/9 of the females are under 18
What fraction of the club members are under 18? Give your answer in its simplest form.
Answer:
3/2
Step-by-step explanation:
The ratio of males to females in a cycling club is 5:3.
1/3 of the males are under 18
2/9 of the females are under 18
The fraction of the club members that are under 18 is calculated as:
Male: Female = Male/Female
We are told in the above question:
1/3 of the males are under 18
2/9 of the females are under 18
Hence:
1/3 / 2/9
= 1/3 ÷ 2/9
= 1/3 × 9/2
= 3/2
The fraction of the club members that are under 18 is 3/2

Answer:
Smallest surface area is of Cuboid B i.e 440 cm²
So, The company will choose cuboid B
Step-by-step explanation:
We need to find the surface area of all cuboids.
Surface Area of Cuboid A:
Length = 6
Breadth = 25
Height = 4
The formula used is: [tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)[/tex]
Putting values and finding surface area:
[tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)\\Surface \ Area \ of \ Cuboid=2((6 \times 25)+(25 \times 4)+(6 \times 4))\\Surface \ Area \ of \ Cuboid=2(150+100+24)\\Surface \ Area \ of \ Cuboid=2(274)\\Surface \ Area \ of \ Cuboid=548\: cm^2[/tex]
So, Surface Area of Cuboid A = 548 cm²
Surface Area of Cuboid B:
Length = 10
Breadth = 6
Height = 10
The formula used is: [tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)[/tex]
Putting values and finding surface area:
[tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)\\Surface \ Area \ of \ Cuboid=2(10 \times 6)+(6 \times 10)+(10 \times 10))\\Surface \ Area \ of \ Cuboid=2(60+60+100)\\Surface \ Area \ of \ Cuboid=2(220)\\Surface \ Area \ of \ Cuboid=440\: cm^2[/tex]
So, Surface Area of Cuboid B = 440 cm²
Surface Area of Cuboid C:
Length = 2
Breadth = 20
Height = 15
The formula used is: [tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)[/tex]
Putting values and finding surface area:
[tex]Surface \ Area \ of \ Cuboid=2((Length\times Breadth)(Breadth \times Height)+(Length \times Height)\\Surface \ Area \ of \ Cuboid=2((2 \times 20)+(20 \times 15)+(2 \times 15))\\Surface \ Area \ of \ Cuboid=2(40+300+30)\\Surface \ Area \ of \ Cuboid=2(370)\\Surface \ Area \ of \ Cuboid=740\: cm^2[/tex]
So, Surface Area of Cuboid C = 740 cm²
So, We get:
Surface Area of Cuboid A = 548 cm²
Surface Area of Cuboid B = 440 cm²
Surface Area of Cuboid C = 740 cm²
The company wants to choose the design having smallest surface area.
So, smallest surface area is of Cuboid B i.e 440 cm²
So, The company will choose cuboid B

Answer:
y +2 = (1/4)(x +1)
Step-by-step explanation:
The given line is in slope-intercept form:
y = mx + b
where the slope (m) is -4 and the y-intercept (b) is +13.
For the perpendicular line, we need a slope that is the opposite reciprocal, or ...
-1/m = -1/(-4) = 1/4
A suitable form for the desired equation is the point-slope form:
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
For m=1/4 and (h, k) = (-1, -2), the equation of the line is ...
y +2 = (1/4)(x +1)

Which of the following equations has no solution?
B= -B+ 2
B + 2= b + 2
B+ b = 2
b + 2 = b-2
Answer:
b+2=b-2
Step-by-step explanation:
The first step to solving this equation is subtract b from both sides. After you do that, you get 2=-2. 2 does not ever equal -2 and that statement is false. Therefore that equation has no solution.
write the equation of the line in y=mx+b that passes through the points (5,10) and (6,12)
Write your answer as a simplified fraction.
Answer:
y = 2x + 0 or y = 2x
Step-by-step explanation:
use slope-intercept form [tex]\frac{y2 - y1}{x2 - x1}[/tex]
12 - 10 = 2
6 - 5 = 1
m value = 2/1 = 2
y=2x+b
to find b plug one of the points in for x and y
Example: 10 = 2(5) + b
solve equation
10 = 10 + b
subtract 10 from both sides
0 = b
Equation of line equals y=2x+0 or simply just y=2x

HELP ASAP Name an angle supplementary to angle5
Answer:
Angle 1
Step-by-step explanation:
The angle supplementary to 5 is 1 because two angles are supplementary when they add up to 180 degrees.
So therefore, on the other/opposite side of angle 5 is angle 1.
The supplementary angle to ∠5 is D. ∠6 as the sum of this two angles is 180°.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know two angles are supplementary if the sum of their measure is 180°.
Now, From the given diagram we can conclude that a straight line is forming with ∠5 and ∠6, So the sum of these angles must be 180° hence supplementary.
Therefore, The angle supplementary to ∠5 is ∠6.
