Answer:
Step-by-step explanation:
6. Use PEMDAS
-3 x (7 + (-3)*2) / 3
-3 x (7 + 9) / 3
-3 x 16 / 3
-48 / 3
-16
7. 9 (x) = -63
X = - 63 /9
X = -7
Answer:
3600000
Step-by-step explanation:
5000000*.28 = 1400000
5000000-1400000 = 3600000
Answer:
x
≈
16
Explanation:
Remember Sine of an angle is
opposite side
hypotenuse
So let the hypotenuse be
x
:
sin
(
47
°
)
=
opposite side
x
sin
(
47
°
)
=
12
x
To solve for
x
, divide
sin
(
47
°
)
by
12
:
x
=
12
sin
(
47
°
)
x
≈
16
This question is actually a lot simpler than it seems
for a quarter think about money - a quarter is 25 cents or 1/4 of a dollar - so 1 and a quarter yard in decimal form is equivalent to 1.25
now you need to find how many 1 and a quarter yards are in 3 yards - to do this you simply divide 3 by 1.25
3/1.25 = 2.4
so julie can cut 2.4 1 and a quarter long pieces from the string

Answer:
J - Janeta's age M - mother's age
A) (J-5) = .2 * (M-5)
B) J = (1/3) * M
Subtracting 5 from both sides of B:
B) J -5 = (1/3)M -5
then we substitute the right side of this into the left side of A and we get
(1/3)M -5 = .2 M -1
.333333333333M -5 = .2M -1
.1111111111111111111M = 4
Mother's Age = 36
Janeta's Age = 12
