Answer:

x = 1

Step-by-step explanation:

P = L + L + W + W

34 = 5x + 5x + 12 + 12

34 = 10x + 24

34-24 = 10x

10 = 10x

10/10 = x

1 = x

1 fourth B minus 10 equals 7

creativ13 [48]

$\frac{1}{4}$ b - 10 = 7
Take 10 to the other side.

$\frac{1}{4}$ b = 17

Multiply by 4 to isolate b
$\frac{1}{4}$ b × 4 = 17 × 4

4 and 4 cancels out

b = 68

Which ordered pair is a solution to the system of linear equations 1/2x-3/4y=11/60 and 2/5x+1/6y=3/10

natka813 [3]

ANSWER

$( \frac{2}{3} , \frac{1}{5} )$

EXPLANATION

The first equation is

$\frac{1}{2} x - \frac{3}{4} y = \frac{11}{60} ...(1)$

The second equation is

$\frac{2}{5} x + \frac{1}{6} y = \frac{3}{10} ...(2)$

We want to eliminate y, so we multiply the first equation by

$\frac{4}{5}$

$\frac{4}{5} \times \frac{1}{2} x - \frac{4}{5} \times \frac{3}{4} y = \frac{11}{60} \times \frac{4}{5}$

$\frac{2}{5} x - \frac{3}{5} y = \frac{11}{75} ...(3)$

We now subtract equation (3) from (2)

$(\frac{2}{3} x - \frac{2}{3} x )+ ( \frac{1}{6} y - - \frac{3}{5}y ) =( \frac{3}{10} - \frac{11}{75} )$

$\frac{1}{6} y + \frac{3}{5}y =\frac{3}{10} - \frac{11}{75}$

$\frac{23}{30}y = \frac{23}{150}$

Multiply both sides by

$\frac{30}{23}$

$\implies \: \frac{30}{23} \times \frac{23}{30}y= \frac{23}{150} \times \frac{30}{23}$

$\implies \: y = \frac{1}{5}$

Substitute into the first equation to solve for x .

$\frac{1}{2} x - \frac{3}{4} \times \frac{1}{5} = \frac{11}{60}$

Multiply to obtain

$\frac{1}{2} x - \frac{3}{20} = \frac{11}{60}$

$\frac{1}{2} x = \frac{11}{60} + \frac{3}{20}$

$\frac{1}{2} x = \frac{1}{3}$

Multiply both sides by 2.

$2 \times \frac{1}{2} x =2 \times \frac{1}{3}$

$x = \frac{2}{3}$

The solution is

$( \frac{2}{3} , \frac{1}{5} )$

Iris is playing a game at the school carnival. There is a box of marbles and each box has a white, a green, and an orange marble

agasfer [191]

There are 4 colors, White ,Green , Red and Orange. And there is a spinner which has 4 sections.
To see how many there are visually you could write out the outcomes.
-White and section 1-White and Section 2-White and Section 3-White and Section 4
-Green and Section 1-Green and section 2-Green and Section 3-Green and Section 4
-Red and Section 1Red and Section 2Red and Section 3Red and Section 4
Orange and Section 1Orange and Section 2Orange and Section 3Orange and Section 4
When you count them up it equals 16 outcomes.
Have a great day :)
