Answer:
she had 16
16
She got c
16 + c
She now has 32
16 + c = 32
I don't know if that's the exact answer, but basically, 16 needs to be added to c, and it needs to equal 32.
Hope this helps! :)
Take out the -13 and add it to 43
Answer:
mean is 5
Step-by-step explanation:
I have another set of choices here:
A. {0.5, 1, 2}
B. {1, 2, 4}
C. {1, 2, 3, 4, 5}
<span>D. {0}
</span>
If you multiply two numbers from a closed set the answer is in the set.
<span>So A is not closed because 2 x 2 = 4 which isn't in the set. Only 0.5, 1, and 2 are in set A. </span>
<span>Try multiplying the largest numbers in sets B, C, and D by themselves. You will soon discover the closed set.</span>
Answer:
x = 7 and y = 0
Step-by-step explanation:
We can either solve by substitution method or by elimination method or both method . We will solve by both the elimination and substitution method.
X+y=7 ---------------------------------------------------(1)
-x+y=-7 -------------------------------------------------(2)
Subtract equation (2) from equation(1)
2x = 14
Divide both-side of the equation by 2
2x/2 = 14/2
x = 7
Substitute x = 7 into equation (1)
x+y=7
7 + y = 7
Subtract 7 from both-side of the equation
7-7 + y = 7-7
y = 0
x = 7 and y =0
