Ok than best best best of luck
Answer:
13
Step-by-step explanation:
(x + 3)^3/2 = 64
√(x + 3)^3 = 64
(x + 3)^3 = 64^2
(x + 3)^3 = (4^3)^2
(x + 3)^3 = (4^2)^3
Same exponent
So
x + 3 = 4^2
x + 3 = 16
x = 13
Substitute:
You are going to substitute each answer choice into your equation.
-2x - y = -7
Let's take the first choice
(3,1)
x y
-2(3) - 1 = -7
-6 - 1 = -7
-7 = -7
The ordered pair that is a solution to -2x - y = -7 is (3, 1).
Answer - (3, 1)
Hope this Helps!!
Answer:
64 1/2
Step-by-step explanation:
6(1/4+5/2)-2
parethesis first 1/4 +5/2 make them the same denominator 1/4 + 10/4 = 11/4
then 6 or 6/1 time 11/4 = 66/4= 16 1/2 - 2 = 64 1/2 i havn't done fractions in awhile so im not a 100% certain
Begin by using simultaneous equations to find the values of x and y.
y=-0.38x+56.6
y=0.38x+43.4
-0.38x+56.6=0.38x+43.4
-0.38x-0.38x=-56.6+43.4
-0.76x=-13.3
x=-13.3/-0.76
x=17.5
y=0.38(17.5)+56.6
y=63.25
Knowing that the initial year was 1968, add 17.5 years to find to find out when the same percent of men and women received a bachelor's degree.
1968+17.5= 1985.5
So, in the year 1985 and half, both men and women got the same number of bachelor's degrees.
