Answer:
Value x = 8 make the equation true .
Step-by-step explanation:
Given : 3x = 24.
To find : Which value of x from the set {5, 6, 7, 8} makes this equation true?
Solution : We have given 3x = 24.
The equations are true when the Left hand side and right hand side of the equation are equal.
Then,
For x = 8 .
3 ( 8) = 24
24 = 24 .
Hence,
Left hand side = Right hand side.
Therefore, Value x = 8 make the equation true .
Answer: x=1.6
y=4.2
Step-by-step explanation:
5.2x - y = 4.1
1.5x + y = 6.7
we will add both equations and you see that the y is getting cancelled
6.7x=10.8
x=10.8/6.7= 1.6
now in any equation we will replace x with 1.6
5.2(1.6)-y=4.1
8.3-y=4.1
-y= 4.1-8.3
-y=-4.2 multiply by -1
y=4.2
False when you multiply numbers you add the exponents.
Answer:
the corresponding angles are equal in similar figures.
Step-by-step explanation:
When two figures are similar then the corresponding angles of the two figures are equal. the side of the figures are in proportional.
for example, when triangle ABC is similar to triangle DEF
then the corresponding angles are equal
<A=<D
<B=<E
<C=<F
so the corresponding angles are equal in similar figures.
Answer: There are children at the circus show.
Step-by-step explanation:
Let be "x" the total number of spectators at the circus show and "c" the number of children at the circus show.
Knowing that of the spectators are men, we can find the remaining:
Since of the remaining number of spectaros are women and there are a total of 132 women, we can write the following equation:
Solving for "x", we get:
Therefore, we get that "c" is:
