Answer:

Step-by-step explanation:

4x - 3y = 8 ------------------(I)

5x - 2y = -11 ------------------(II)

Multiply the equation (I) by (-5) and equation (II) by 4 and then add.

(I)*(-5) -20x + 15y = -40

(II)*4 20x - 8y = -44 {Now add, x will be eliminated}

7y = -84

y = -84/7

y = -12

Plugin y = -12 in equation (I)

4x - 3*(-12) = 8

4x + 36 = 8

4x = 8 - 36

4x = -28

x = -28/4

x = -7

If the ratio of purple bikes to red bikes is 8 to 12 and there are a total of 100 bikes, how many of them are purple? * 40 purpl

Marrrta [24]

Answer:

Step-by-step explanation:

sum the parts of the ratio, 8 + 12 = 20 parts

Divide the total by 20 to find the value of one part of the ratio

100 ÷ 20 = 5 ← value of 1 part of the ratio , thus

8 parts = 8 × 5 = 40 ← number of purple bikes

If a concrete mix contains 1-1/2 cubic feet of gravel, 1/2 cubic foot of water,

Karolina [17]

Answer:

The correct answer is "50%".

Step-by-step explanation:

The given values are:

Gravel,

= $(1-\frac{1}{2} )$

Water,

= $\frac{1}{2}$

Cement,

= 1

Sand,

= 2

Now,

The total mixture will be:

= $Gravel+Water+Cement+Sand$

By substituting the values, we get

= $(1-\frac{1}{2} )+\frac{1}{2} +1+2$

= $\frac{1}{2} +\frac{1}{2} +1+2$

= $4 \ cubic \ feet$

hence,

The percentage of sand will be:

= $\frac{Sand}{Total}\times 100$

= $\frac{2}{4}\times 100$

= $50$ %
