what is the value of x in the equation 3(x-2)+4x=10(x+1)
Answer:
-16/3 =x
Step-by-step explanation:
3(x-2)+4x=10(x+1)
Distribute
3x -6 +4x = 10x +10
Combine like terms
7x -6 = 10x+10
Subtract 7x from each side
7x-6-7x = 10x-7x +10
-6 = 3x+10
Subtract 10 from each side
-6-10 = 3x+10-10
-16 = 3x
Divide by 3
-16/3 = 3x/3
-16/3 =x

Answer:
∠ Q = 75°
Step-by-step explanation:
Since PR and PQ are equal then the triangle is isosceles, thus
the base angles R andQ are congruent
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
x + 2x + 15 + 2x + 15 = 180, that is
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30
Thus
∠ Q = 2x + 15 = 2(30) + 15 = 60 + 15 = 75°
Simplify the expression:
(1 + 5h)(4)
Answer:
20h + 4
Step-by-step explanation:
It's easy. Just disperse the multiplying by 4 to the others in the first group.
Multiply 1 by 4, and you get 4.
Multiply 5h by 4, and you get 20h.
The answer is 20h + 4.

what type of triangle is ️abc as defined by its sides and angles
a. acute scalene
b. obtuse isosceles
c. right scalene
d. acute isosceles
Answer: d) acute isoceles
Step-by-step explanation:
it has 2 acute angles and it's isoceles because it has 2 sides of equal length
Answer:
d. acute isosceles
Step-by-step explanation:
ABC had two sides that are equal so it is an isosceles triangle
<B = 90-44 = 46
A and C must be equal
A + B + C = 180
A + 46 + B = 180
2A = 180- 46
2A = 134
A = 67 so C = 67
All angles are acute

Claire and Richard are both artists. Claire uses the polynomial 50x^2+250 to decide how much to charge.Richard uses the polynomial 49x^2+350 to charge how much to charge for his painting.In each polynomial x is the height of the paintings feet. To the nearest tenth what height will both Claire and Richard charge for the same amount for a painting?
Answer:
The height of the painting has to be 10 feet for both Claire and Richard to charge the same amount.
Step-by-step explanation:
The polynomial expression representing the charge for Claire's paintings is:
C = 50x² + 250
The polynomial expression representing the charge for Richard's paintings is:
R = 49x² + 350
Here x represents the height of the paintings feet.
Now compute the value of x such that both Claire and Richard charge the same amount as follows:
C = R
50x² + 250 = 49x² + 350
50x² - 49x² = 350 - 250
x² = 100
x = 100
Thus, the height of the painting has to be 10 feet for both Claire and Richard to charge the same amount.
There are 420 grams of sodium in 3 cans of soup. Which equation finds the number of grams of sodium, s, in 1 can of soup? A 1s=34201 over s is equal to 3 over 420 B 3s=14203 over s is equal to 1 over 420 C s420=31s over 420 is equal to 3 over 1 D s1=3420s over 1 is equal to 3 over 420
Answer:
[tex]1\ can = 140g[/tex]
Step-by-step explanation:
Given
[tex]420 g = 3\ cans[/tex]
Required
Determine the number of grams in 1 can
[tex]420 g = 3\ cans[/tex]
Reorder
[tex]3\ cans = 420 g[/tex]
Divide both sides by 3
[tex]\frac{3\ cans}{3} = \frac{420 g}{3}[/tex]
[tex]1\ can = 140g[/tex]
Hence;
There are 140 grams in 1 can

Answer:
The percentage was 25% which was an increase.
Step-by-step explanation:
150 - 120 x 100% = 25%
120
150 - 120 = 25% (30)
Answer:
The percentage was 25% which was an increase.

Which demonstrates the distributive property? *
a + b = b + a
O (a + b) + c = a + (b + c)
a(b + c) = ab + ac
a + 0 = a
Answer:
a(b + c) = ab + ac demonstrates the distributive property ⇒ C
Step-by-step explanation:
The distributive property is the product of a number by the sum of the other two numbers equal to the sum of the product of the number with each of the other two numbers.
Example: x(y + z) = xy + xz
Let us check the choices to find which of them demonstrates the distributive property
∵ a + b = b + a
→ Adding a and b equals to adding b and a,
∴ It demonstrates the commutative property
∵ (a + b) + c = a + (b + c)
→ Adding the sum of a and b to c equals to adding c to the sum of a and b
∴ It demonstrates the associative property
∵ a(b + c) = ab + ac
→ Multiplying a by the sum of b and c equals the sum of the products
of a, b and a, c
∴ It demonstrates the distributive property
∵ a + 0 = a
→ The additive identity is zero
∴ It demonstrates the additive identity property
∴ a(b + c) = ab + ac demonstrates the distributive property

ben payed $900 for a sofa. The price of the sofa Juana was 2/3 the price ben payed. How much did Juana pay for her sofa?
Answer: $600
Step-by-step explanation:
Find 2/3 of $900.
To do this, we have to get 9 and divide by 3.
9 ÷ 3 = 3
Multiply 3 by 2. You get 6.
Add two zeros.
You will get $600.

What is the solution to the inequality 5.25 – b ≥ 6.5? A number line going from negative 5 to positive 5. A solid circle appears between negative 1 and negative 2. The number line is shaded from the circle to negative 5. A number line going from negative 5 to positive 5. An open circle appears between negative 1 and negative 2. The number line is shaded from the circle to negative 5. A number line going from negative 5 to positive 5. A solid circle appears between negative 1 and negative 2. The number line is shaded from the circle to positive 5. A number line going from negative 5 to positive 5. An open circle appears between negative 1 and negative 2. The number line is shaded from the circle to positive 5.
Given:
The inequality is
[tex]5.25-b\geq 6.5[/tex]
To find:
The solution of the given inequality on the number line.
Solution:
We have,
[tex]5.25-b\geq 6.5[/tex]
Subtract 5.25 from both sides.
[tex]5.25-b-5.25\geq 6.5-5.25[/tex]
[tex]-b\geq 1.25[/tex]
Multiply both sides by -1 and change the sign of inequality.
[tex]b\leq -1.25[/tex]
The value of b always less than or equal to -1.25. Since -1.25 included in the solution set, therefore there is a solid circle on -1.25.
-1.25 lies between -2 and -1. It means the solid circle lies between -1 and -2.
[tex]b\leq -1.25[/tex], so the number line is shaded from the circle to negative 5.
A number line going from negative 5 to positive 5 is the required solution if a solid circle appears between negative 1 and negative 2. The number line is shaded from the circle to negative 5.
Therefore, the correct option is A.
