6w-2(4+w)=w+7 solve for w

Answers

6w - 2(4 + w) = w + 7
6w - 8 - 2w = w + 7
4w - 8 = w + 7
(4w - 8) + 8 = w + 7 + 8
4w = w + 15
4w - w = (w + 15) - w
3w = 15
3w ÷ 3 = 15 ÷ 3
w = 5

Why is 31.m greater than 450cm

in the school Marching band the ratio of trumpet players to drummers was 5 to 2 . if there were six drummers in the marching band, how many trumpet players were there?

Answers

We have an equation: 5/? = 2/6

Cross multiply:
2*? = 5*6
⇒ ?= 5*6/2= 15

There were 15 trumpet players~

A fruit company delivers its fruit in two types of boxes:large and small. A delivery of 9 large boxes and 7 small boxes has a total weight of 216 kilograms. A delivery of 3 large boxes and 5 small boxes has a total weight of 90 kilograms. How much does each type of boxes weigh?

Answers

Answer:

The weight of the larger box is 18.75 kg

The weight of the small box is 6.75 kg

Step-by-step explanation:

Let

x -----> the weight of large box

y ----> the weight of small box

we know that

The system of equations is equal to

9x+7y=216 -----> equation A

3x+5y=90 -----> equation B

Solve the system of equations by graphing

Remember that the solution is the intersection point both graphs

using a graphing tool

The solution is the point (18.75,6.75)

therefore

The weight of the larger box is 18.75 kg

The weight of the small box is 6.75 kg

Angles U and V are supplementary angles. The ratio of their measures is 7:13 Find the measure of each angle

Answers

If $u$ and $v$ are supplementary angles, then

$u+v=180^(\circ)~~~~~\mathbf{(i)}$

The ratio of $u$ and $v$ is $(7)/(13):$

$(u)/(v)=(7)/(13)\n\n\n u=(7v)/(13)~~~~\mathbf{(ii)}$

Substitute $\mathbf{(ii)}$ into $\mathbf{(i)}:$

$(7v)/(13)+v=180^(\circ)\n\n\n \left((7)/(13)+1 \right )\cdot v=180^(\circ)\n\n\n \left((7)/(13)+(13)/(13) \right )\cdot v=180^(\circ)\n\n\n (20)/(13)\cdot v=180^(\circ)\n\n\n v=180^(\circ)\cdot (13)/(20)\n\n\n \boxed{\begin{array}{c} v=117^(\circ) \end{array}}$

From $\mathbf{(i)},$ we find the measure of $u:$

$u=180^(\circ)-v\n\n u=180^(\circ)-117^(\circ)\n\n \boxed{\begin{array}{c} u=63^(\circ) \end{array}}$
