The first and last one are true!
80/75 in simplest terms is 16/15
Divide both the numerator and denominator by 5
Answer:
147
Step-by-step explanation:
E = greatest common factor of 22 and 30 = 2
F = least common multiple of 3 and 8 = 24
G = 3 * (7 + 10) = G + 30 = 81
3 * 7 + 3 * 10 = G + 30
21 + 30 = G + 30
51 = G + 30
G = 81
H = 5 * (3 + H) = 15 + 45 = 40
5 * 3 + 5 * H = 15 + 45
15 + 5 * H = 60
20 * H = 60
H = 60 - 20
H = 40
E = 2 + F = 24 + G = 81 + H = 40
2 + 24 + 81 + 40 = 147
This was fun lol
Answer:
30°,60°,90°
Step-by-step explanation:
<u>Let </u><u>:</u><u>-</u><u> </u>
<u>As </u><u>we</u><u> know</u><u> </u><u>:</u><u>-</u><u> </u>
<u>So </u><u>that</u><u> </u><u>,</u>
- x + 2x + 90 = 180
- 3x = 90
- x = 90/3
- x = 30

Answer:
See solution below
Step-by-step explanation:
Given the following expression
1) 24+r
If r = 9
24 + r = 24+9
= 33
2) 2a+3
If a = 10
Substitute
2(10)+3
= 20+3
= 23
3) BC+12.3
b = 9
c = 4
Substitute
= 9(4)+12.3
= 36+12.3
= 48.3
4) p÷q
Given p = 24 and q = 8
p÷q = 24÷8
p÷q = 3
5) 4c-7.8
If c = 4
Substitute
= 4(4)-7.8
= 16-7.8
= 8.2
6) c-a
a = 3
c = 17
Substitute
= 17-3
= 14
Hence c-a = 14
7) a ÷ 2c ; a = 20, c = 2
Substitute
a÷2c
= a/2c
= 20/2(2)
= 20/4
= 5
8) 3x-14
If x = 5
Substitute
= 3(5)-14
= 15-14
= 1
9) 1.5 + y² ; y = 6
Substitute
= 1.5+6²
= 1.5+36
= 37.5
10) t/5 + 6 ; t = 45
substitute the value of t given into the expression
= 45/5 + 6
= 9 + 6
= 15
