-14x = -7 - 7y
-10x = -15 - 7y...multiply by -1
---------------
-14x = -7 - 7y
10x = 15 + 7y (result of multiplying by -1)
-------------add
-4x = 8
x = -8/4
x = -2

-10x = -15 - 7y
-10(-2) = -15 - 7y
20 = -15 - 7y
20 + 15 = -7y
35 = -7y
-35/7 = y
-5 = y

solution is (-2,-5)

A local garden club had 14 members with a mean age of 34. Then two new members joined. One was 24 years old, and the other was 3
Vladimir79 [104]
<h3>Answer:</h3>

The mean age decreased.

<h3>Step-by-step explanation:</h3>

I find it convenient to look at the additions with respect to the current mean age.

The current total age is 14×34. We have added members with ages (34 -10) and (34 +2), so the new total age is ...

... (34×14) + (34 -10) + (34 +2) = (16×34) - 8

Dividing this total by 16 will give the new mean age. (We already know it is less than 34.)

... ((16×34) -8)/16 = 34 - 1/2 = 33 1/2 . . . new mean age; a decrease

d1i1m1o1n [39]

Answer:

x = 3

Step-by-step explanation:

(8x-8)^{3/2}=64

Multiply both sides by the exponent 2/3.

8x - 8 = 64^{2/3}

Solve for the exponent.

8x-8=16

Add 8 to both sides.

8x = 16+8

8x=24

Divide 8 into both sides.

x=24/8

x=3
