84 + 48 = 132
132 divided by 4 = 33
Misty will need 33 pages if she puts 4 photos on each page.
Answer:
15 degrees, 75 degrees
Step-by-step explanation:
Call the first angle's measurement m
∠
1
.
The second angle is 5 times this, or 5
(
m
∠
1
)
.
Since the two angles are complementary (have a sum of 90
˚
), we can relate the two angles him as follows:
m
∠
1
+
5
(
m
∠
1
)
=
90
6
(
m
∠
1
)
=
90
m
∠
1
=
15
Since m
∠
2
is 5
times this, m
∠
2
=
15
×
5
=
75
.
I'M NOT TO SURE ABOUT THIS ANSWER BUT I HOPE THIS CAN HELP SOME PEOPLE.
Solutions are 3 and - 5.
Step-by-step explanation:
Step 1:
Given equation is 3x² + 6x = 45. Factorize the equation to get the solutions.
⇒ 3x² + 6x - 45 = 0
⇒ x² + 2x - 15 = 0
⇒ x² + 5x - 3x - 15 = 0 (Product and Sum Method where product of coefficients = - 15 and sum = 2)
⇒ x (x + 5) - 3(x + 5) = 0
⇒ (x - 3)(x + 5) = 0
⇒ x = 3, - 5
Answer:
57
Step-by-step explanation:
exterior angles add up to 360 so'
9x+1+5x+12+10x-37
24x-24=360
24x=384
x=16
10(16)-37
160-37
123
180-123
= 57
