Answer:
the base or (b) is 10. The height or (H) is 15. The area of the triangle is 75.
Step-by-step explanation:
Answer:
D. joint variation
Step-by-step explanation:
y = 14x/z
y is directly proportional to x and inversely proportional to y
Constant of proportionality = 14
Direct variation is given as
y = kx
Where, k = constant of proportionality
Inverse variation is given as
y = k/z
Where, k = constant of proportionality
When they are jointly combined
y = kx/z
8(5+w)
Multiply 8x5 then 8xw
40+8w
Answer:
14 scarves
Step-by-step explanation:
Change the divisor 3.75 to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend the same, 2 places to the right.
We then have the equations:
5250 ÷ 375 = 14
and therefore:
52.5 ÷ 3.75 = 14
Both calculated to 0 decimal places.
How you start the equation is by plugging
3
into both of the
x
's in the problem to make it:
f
(
3
)
=
3
(
3
)
−
4
Next, you multiply the
3
(
3
)
to get
9
and subtract
4
. So in the end, you leave the
f
(
3
)
and
9
−
4 is
5
, so the
y
in the equation is
5
.
The answer would be written as
f
(
3
)
=
5
