Answer:
-7 and 21
Step-by-step explanation:
y-2y=7 (sub x=7 to the equation)
-y=7
y=-7 (not sure of its correct)
if y=-7,
x-2(-7)=7 (sub y=-7 into equation)
x-14=7
X=7+14
X=21
4³ ⋅ (100 ÷25) − 5^0
[parenthesis goes first, then exponents]
[any coefficient with zero exponent is equal to 1]
64 · 4 - 1
[multiplication, then subtraction]
256 - 1
<u>255</u>
<h3>
It is equivalent to 2a+2b</h3>
We use the distributive property.
Multiply the outer term 2 by each term inside ('a' and b)
2 times a = 2a
2 times b = 2b
We add those results to get 2a+2b. We cannot combine these terms as they are not like terms.
