Answer:

4 : 12 : 15

Step-by-step explanation:

S : J = 1 : 3

J : P= 4 : 5

Using John's ratio to find a common ratio for all

S : J

(1 : 3)4 = 4 : 12

J : P

(4 : 5)3 = 12 : 15

Therefore our ratio is

S : J : P

4 : 12 : 15

What value of x makes the equation −2x−(−5−4x)=−5(2x−7) true?
Anestetic [448]

Answer:

-2x - (-5 - 4x) = -5(2x - 7)

-2x + 5 - 4x = -5 * 2x - 5 * (-7)  

-6x + 5 = -10x - 35

-6x + 5 + 10x = -10x - 35 + 10x

4x + 5 = -35

4x + 5 - 5 = -35 - 5

4x = -40

4x/4 = -40/4

x = 10

Answer is H. p/5 = 8

Given:
1/5 of the plants in a vegetable garden are cucumber plants.
8 cucumber plants.

Find the total number of plants in the vegetable garden.

8 ÷ 1/5 = p

Steps in dividing fractions.
1) Get reciprocal of 2nd fraction. 1/5 is the 2nd fraction. Its reciprocal is 5/1

2) multiply 1st fraction to the reciprocal of the 2nd fraction
8 * 5/1 = p

3) 8*5 = p ⇒ p = 40

p * 1/5 = 8
p/5 = 8

40/5 = 8
8 = 8

Answer:

Measure of ∠B = 51°.

Step-by-step explanation:

The sum of the measures of any triangle will always add up to 180°.  Also the sum of two supplementary angles, or angles that are side by side on a straight line, will also add up to 180°.  In order to find the measure of ∠B, you need to first find the measure of ∠C.  ∠C is supplementary to the angle of 113°, so we can find ∠C: 180 - 113 = 57°.  Now that we know ∠A and ∠C, we can solve for ∠B:  180 = 72 + 57 + ∠B or 180 = 129 + ∠B, subtracting 129 from both sides, we get ∠B = 51°.
