Answer:
(a) 150
(b) 384
(c) 84
(d) 261
(e ) 480
Step-by-step explanation:
(a)
Let 'a' be a number such that the half of his third is 25; i.e.
Hence, the number is 150.
(b)
Let 'b' be the number such that the quarter of his half is 48 i.e.
Hence the number is 384.
(c)
Let 'c' be the number such that the third quarter or, increased by 17 is 80.
Hence, the number is 84.
(d)
Let 'd' be the number such that its triplet, reduced by 28 is 755
Hence the number is 261.
(e
Let 'e' be the number such that double his third, increased by 80 is 400.
Hence, the value of the number is 480.
Answer:
x=15º
Step-by-step explanation:
A triangle's angles add up to 180º.
∠A=30º
∠C=180º-45º
∠B=xº
To find ∠B we have to first find ∠C.
Since ∠C does not have an angle, knowing that a straight line is 180º we can subtract it from 45º to find ∠C.
180-45=135
∠C=135º
Now add ∠A and ∠C.
30+135=165
Subtract the sum from 180º
180-165=x
x=15º

Answer:
13) 90-18 = 72
14) 108/9 = 12
15) 66+34 = 100
16) 7*8 = 56
Step-by-step explanation:
All you need to do is take the second term of each equation and move it to the other side. So for number 16 we just need to move the 8 from the left to the right. This is as simple as multiplying both sides by 8 to get:
8*(56/8) = 8(7)

V
56 = 8*7
And that would be the answer to number 16!
