Answer: x = -1
Step-by-step explanation:
x + 5 - 4x = 8
-3x + 5 = 8
-3x = 8 - 5
-3x = 3
-3x/3 = 3/3
-x = 1
x = -1
Answer:
x = 14
Step-by-step explanation:
See the diagram of the triangle attached.
We have Δ RST where, ∠ RST = 7x -54 and ∠ SRT = ∠ STR {Since, given that, RS = ST}
Now, if ∠ STU = 8x, then ∠ STR = 180 - 8x {Since, ∠ STU and ∠ STR are supplementary}
So, ∠ SRT = ∠ STR = 180 - 8x
Now, from Δ SRT, ∠ RST + ∠ SRT + ∠ STR = 180
⇒ 7x - 54 + 180 - 8x + 180 - 8x = 180
⇒ 9x = 126
⇒ x = 14 (Answer)
Answer:
9%
Step-by-step explanation:
71 - 65 = 6 (final value - initial value)
6 / 65 = 0.0923... (divide the answer by the initial value)
0.0923 * 100 = 9.23% (Multiply by 100 to find the percentage)
Round 9.23 to the nearest whole number → 9%
Answer:
42,44,46
Step-by-step explanation:
we first divide the 132 by the 3 which gives 44
since the numbers involved are even numbers and we know even numbers are numbers divisible by 2 we subtract 2 from the 44 and also add 2 to the 44 the get the rest of the two numbers which is from the above explanation
(44-2),44,(44+2)
42,44,46
we can check whether the above numbers are correct by adding to see whether we get 132
42+44+46=132 which are consecutive even numbers
0 , 4 , 8 , 12 , .... that’s what you can do to answer that question
