Problem #7 PLEASE HELP ;(

Answer:

Yes

6(x+0.4) is equivalent to 3(2x+0.8)

Step-by-step explanation:

Given in the questions two expressions

6(x + 0.4)

3(2x + 0.8)

We will apply distributive law

It is a law relating the operations of multiplication and addition, stated symbolically

<h3>a(b + c) = ab + ac</h3><h3 />

6(x + 0.4)

= 6(x) + 6(0.4)

= 6x + 2.4

3(2x + 0.8)

= 3(2x) + 3(0.8)

= 6x + 2.4

Since both equations when expanded have same answers, hence they are equivalent

Simora [160]
0.04= \frac{4}{100}\to\frac{1}{25} \\\\ \frac{1}{10} \ of \ x= \frac{1}{25} \\\\ \frac{1}{10}*x=\frac{1}{25} \\\\ \frac{x}{10}=\frac{1}{25} \\\\ \boxed{x=\frac{10}{25}\to\frac{2}{5}}

How would I solve questions 22 &amp; 23?
frosja888 [35]
In a parallelogram, adjacent angles make 180°

So in 22

11x + 11 + 70 = 180
11x = 99
x = 9

In 23

12x + 10 + 50 = 180
12x = 120
x = 10

What is the value of y in the equation 6.4x + 2.8y = 44.4, when x = 3?
luda_lava [24]
I think the value of y would be 9
because if you put 3 in place of x the equation would be
6.4(3)+2.8y then you would simplify it to 19.2+2.8y
19.2-44.4=25.5
25.2/2.8=9 which is the value of y

answer=9
