"Jeannie is 8 years older than her younger sister April"
this translates to
J = A + 8
"added together, their ages equal 198"
this translates to
A + J = 198
Plug the first equation into this one and we get
A + A + 8 = 198
add like terms
2A + 8 = 198
subtract 8 from both sides
2A = 190
divide both sides by 2
A = 190/2 = 95
Therefore April is 95 years old
Answer:
A. ASA
Step-by-step explanation:
Two angles and the side between them are marked congruent. In the congruence theorem designators, A stands for Angle, and S stands for side. When there is a congruent side between two corresponding congruent angles, the ordering of the designators is A - S - A.
The ASA postulate applies.
Answer:
Step-by-step explanation:
y ∝ x^2
Introducing the proportionality constant, we have
y = kx^2
Given : y= 18 when x = 3
substitute the given values in order to get the constant
i.e 18 = k x 3^2
18 = 9k
k = 2
therefore the formula connecting x and y
⇒ y = 2x^2
To find y if x is 4, just substitute x = 4 into the formula connecting x and y
i.e y = 2 x 4^2
= 2 x 16
= 32
Answer:
8
Step-by-step explanation:
3 + 3 + 3 - 4 - 4 + 3 + 3 + 3
It takes a minimum of 8 jumps to land exactly on the 10th step.
