solve this equation 5x+17= 42
Answer:
x = 5
Step-by-step explanation:
5x + 17 = 42
5x = 25
x = 5
Answer:
x = 5
Step-by-step explanation:
5x+17= 42
Subtract 17 from each side
5x+17-17= 42-17
5x = 25
Divide each side by 5
5x/5 = 25/5
x = 5
Which is the correct calculation for the volume of the prism?
A prism has a length of 8 millimeters, height of 2 and one-half millimeters, and width of 8 and one-half millimeters.
2 and one-half + 8 + 8 and one-half = 19 mm3
2 and one-half times 8 + 8 and one-half = 28.5 mm3
8 times 8 and one-half = 68 mm3
2 and one-half times 8 times 8 and one-half = 170 mm3
Answer:
its D
Step-by-step explanation:
The correct calculation for the volume of the prism is 2 and one-half times 8 times 8 and one-half = 170 mm3
What is a volume?Volume is defined as the space occupied by any object in the three-Dimensions. All three parameters are required for the volume like length, width and height of cube or cubes.
The volume will be calculated as:-
V = L x W x H
V = [tex]2\dfrac{1}2}[/tex] x 8 x [tex]8\dfrac{1}{2}[/tex]
V = ( 5/2) x 8 x ( 17/2 )
V = 170 mm³
Therefore correct calculation for the volume of the prism is 2 and one-half times 8 times 8 and one-half = 170 mm3

Answer: 110
Step-by-step explanation: This is actually very simple. Al you have to do is to find the area of the 3 rectangles, which adds up to be 96, and find the area of the triangles, which adds up to be 14. You then have to add 96 and 14, which results in 110.
Without drawing the graph of the function y=1.2x−7, see if the graph passes through points: (100; 113)
Answer:
(100,113) is on the graph of y = 1.2x -7
Step-by-step explanation:
y=1.2x−7
Substitute the point in and see if the equation is true
113 = 1.2 (100) -7
113 =120 - 7
113 = 113
This is true, so the point is on the graph

Answer:
You can't you have to use 20 trees since 20 divided by 5 is 4.
So using 10 would make it 10 divided by 5 which is 2.
And the trees can't be halve so it's 20. 10 is impossible.

For what value of x the relation S: {(x2+3,4), (5,2)} is not a function?
Answer:
x = ±sqrt(2)
Step-by-step explanation:
It is not a function if the same input goes to 2 different outputs
x^2 +3 =5 would cause the same input to go to 2 different outputs
Subtract 3 from each side
x^2 +3-3 =5-3
x^2 = 2
Take the square root of each side
sqrt(x^2) = ±sqrt(2)
x = ±sqrt(2)
Answer:
x = sqrt(2), -sqrt(2)
Step-by-step explanation:
For a function, there cannot be multiple outputs for the same input, therefore x²+3 should not be 5
x² + 3 = 5
x² = 2
x = +/- sqrt(2)

A system of equations is a collection of related equations
The system of equations that can be used to solve [tex]12x^3 - 5x = 2x ^2 + x + 6[/tex] [tex]y = 2x ^2 + x + 6[/tex] and [tex]y= 12x^3 - 5x[/tex]
The equation is given as:
[tex]12x^3 - 5x = 2x ^2 + x + 6[/tex]
Split the above equation into 2, and set both equations to 0
[tex]12x^3 - 5x = 0[/tex]
[tex]2x ^2 + x + 6 = 0[/tex]
Replace the "0" with y, in both equations
[tex]12x^3 - 5x = y[/tex]
[tex]2x ^2 + x + 6 = y[/tex]
Rewrite the equations as:
[tex]y = 2x ^2 + x + 6[/tex]
[tex]y= 12x^3 - 5x[/tex]
Hence, [tex]y = 2x ^2 + x + 6[/tex] and [tex]y= 12x^3 - 5x[/tex] can be used to solve [tex]12x^3 - 5x = 2x ^2 + x + 6[/tex]

Find the angle represented by x (rounded to the nearest tenth of a degree). A) 32.6° B) 36.4° C) 37.8° D) 38.7°
Answer:
The angle is 49.63°, approximately.Step-by-step explanation:
In the image attached, you can observe that the angle we need to find is an acute angle of a right triangle, where its hypothenuse is 21 units long and its opposite leg is 16 units long.
Having these elements, we can use the sine trigonometric reason to find the angle.
[tex]sin(x)=\frac{opposite \ leg}{hypothenuse} =\frac{16}{21}\\ x=sin^{-1}(\frac{16}{21} ) \approx 49.63\°[/tex]
Therefore, the angle is 49.63°, approximately.
Faith makes greeting cards with colored paper. She plans to make 15 of the cards out of red paper. She has 25 sheets of colored paper in all. If she uses all the colored paper she has, how many sheets are a color other than red?
Answer:
5
Step-by-step explanation:
because..............
Using fraction, the sheets are a color other than red is 5.
What is fraction?Fraction is a "number are expressed as quotient, where numerator is divided by denominator".
According to the question,
Faith has 25 sheets of colored paper. She plans to make 15 of the cards out red paper.
[tex]\frac{15}{25}[/tex] = [tex]\frac{3}{5}[/tex]
5 - 3 =2
Fraction 5 parts of sheets is equal to 25, 3 parts of sheet is equal to 15.
5 = 25
2 = x
5 × 5 = 25
2 × 5 = 10
Hence, using fraction the number of sheets are a color other than red is 5.

The side on a clip board appears to be a right triangle. The leg lengths are 2 millimeters and 2.1 millimeters and the hypotenuse is 2.9 millimeters. Is the side of the clip a right triangle?
Answer:
Yes, it is a right angle triangle
Step-by-step explanation:
Let leg lengths be y and z
Y = 2mm
Z = 2.1mm
Let x represent hypothenus
X = 2.9mm
To find out if it's a right angle triangle, we'll use pythagorean theorem since it's true for all right angle triangles I.e the square of the hypothenus is equal to the square of both sides(opposite and adjacent)
x² = y² + z²
x² = 2² + 2.1²
x² = 4 + 4.41
x² = 8.41
Take the square root of both sides
x = √(8.41)
x = 2.9mm
Therefore since the square of two other sides equal the square of the hypothenus, the side of the clip is a right angle triangle
