Answer:
x=2
a=19
Step-by-step explanation:
2x+3=7
2x+3-3=7-3
2x=4
2x/2=4/2
x=2
418=-22a
418/(-22)=-22a/(-22)
19=a
Answer:
d. 3x + 6 = 26
Step-by-step explanation:
<u>Definitions</u>
- Integer: a whole number that can be positive, negative or zero.
e.g. ..., -3, -2, -1, 0, 1, 2, 3, ... - Even number: an integer that is exactly divisible by two. For example, 2, 4, 6, 8 are all positive even numbers.
- Consecutive: following one after the other in order.
<u>The sum of three consecutive even integers</u>
Let x be the first even integer.
As there is a <u>difference of 2</u> between <u>consecutive even integers</u>, the next even integer after x will be (x + 2).
Therefore, the next even integer after (x + 2) will be (x + 2) + 2 = (x + 4).
So "the sum of three consecutive even integers is twenty-six" is:
x + (x + 2) + (x + 4) = 26
<u>To solve</u>
⇒ x + (x + 2) + (x + 4) = 26
⇒ x + x + 2 + x + 4 = 26
⇒ 3x + 6 = 26
(Please note that there are no three consecutive even integers that sum to 26, so the problem cannot be solved).
Answer:
acute angle
Step-by-step explanation:
it is very simple question because when small terminal us in 10 and big 8ne is on 12 in the 12 hour clock then it is found an acute angle

Answer:
14%
Step-by-step explanation:
Given :
Bear voters = 14
Lion voters = 86
Percentage of students who voted bear :
(Bear voters / total number of Voters) * 100%
Total number of voters = (bear voters + lion voters) = (14 + 86) = 100
Percentage of students who voted bear :
(14 / 100) * 100%
0.14 * 100%
= 14%
85/15 is 5 2/3
so, to find 85% with 15%, you would multiply 12 (also 15%) by 5 2/3.
12*5 2/3=68.
you could also find it using the 1% method:
1% of 15 is .15.
.15*85=68.
Hope this helps!
