Answer:
A
Step-by-step explanation:
I just did it
To find your answer you must substitute y for 0.8
4x + (8)(0.8) = 40
Now solve for x
====================================================================
SOLVING...
<span>4x + (8)(0.8) = 40
</span><span>4x + 6.4 </span>= <span>40
</span>
Subtract 6.4 from each side
<span><span><span>4x</span>+ 6.4 </span>− 6.4 </span>= <span>40 − <span>6.4
</span></span>4x = 33.6
Divide each side by 4
4x ÷ 4 = 33.6 ÷ 4
x = 8.4
Answer:
Yes. Plug in your x and y into the first given equation and you'll see why.
(7) ≥ -(2)+1
7 ≥ -1 (7 is greater than or equal to -1)
...As well as the second equation.
(7) < 4(2)+2
7 < 8+2
7 < 10 (7 is less than 10)
Step-by-step explanation:
First, identify the terms.
23
+6c
+8d
-7d
-6
Now combine like terms. Like terms are terms with the same variable (i.e. 1x and 3x)
23 and -6
6c
8d and -7d
Now combine!
23 - 6 = 17
6c = 6c
8d - 7d = 1d
So the answer is 17 + 6c + 1d
