The answer is $8.75. You have to find what one costs which is 1.25 so if you have 7. 1.25 times 7 is $8.75

5 divided by 4 = 1.25
Since each muffin equals $1.25, then we must multiply it by the number of muffins to get the answer.

1.25 x 7 = 8.75.
7 muffins are the cost of $8.75.

We know that
<span>An electrician can wire a house in ------------> 20 hours
so
100%----------------> 20 hours
X-------------------> 12 hour
x=12*100/20----> x=60%

that means
</span><span>the apprentice in 12 hours complete the (100-60)----> 40%

</span>the apprentice in 12 hours complete -------> 40%
x hours------------------------------------> 100%
x=100*12/40-----> x=30 hours

the answer is
30 hours

(x – 3)(4x + 2) using the distributive property. Select the answer choice showing the correct distribution

Nataly [62]

The distributive property: a(b + c) = ab + ac

(x - 3)(4x + 2) = (x)(4x + 2) + (-3)(4x + 2)

= (x)(4x) + (x)(2) + (-3)(4x) + (-3)(2) = 4x² + 2x - 12x - 6

Which equation has infinite solutions?

AnnyKZ [126]

The equation that has an infinite number of solutions is $2x + 3 = \frac{1}{2}(4x + 2) + 2$

<h3>How to determine the equation?</h3>

An equation that has an infinite number of solutions would be in the form

a = a

This means that both sides of the equation would be the same

Start by simplifying the options

3(x – 1) = x + 2(x + 1) + 1

3x - 3 = x + 3x + 2 + 1

3x - 3 = 4x + 3

Evaluate

x = 6 ----- one solution

x – 4(x + 1) = –3(x + 1) + 1

x - 4x - 4 = -3x - 3 + 1

-3x - 4 = -3x - 2

-4 = -2 ---- no solution

$2x + 3 = \frac{1}{2}(4x + 2) + 2$

2x + 3 = 2x + 1 + 2

2x + 3 = 2x + 3

Subtract 2x

3 = 3 ---- infinite solution

Hence, the equation that has an infinite number of solutions is $2x + 3 = \frac{1}{2}(4x + 2) + 2$
