Answer:
Step-by-step explanation:
ΔJKL ~ ΔMNP
So, the sides of both of the triangles are proportional.
Taking proportionality of their sides.
=> 
Cross Multiplying
20 * 30 = 25(4x-4)
600 = 100x - 100
Adding 100 to both sides
600+100 = 120x
700 = 100x
Dividing both sides by 100
700/100 = x
x = 7
Answer:
3 tenths
Step-by-step explanation:
One candy bar
= 1 candy bar
= 1.0, or 10 tenths (one tenth is 0.1)
If Theo eats 0.7 of a candy bar, we know that
1.0 - 0.7 = 0.3
0.3 = 3 *0.1 (one tenth)
Therefore, the answer is 3 tenths.
Eliminate x's by adding te 2 equations
add them
-2x+15y=24
<u>2x+9y=24 +</u>
0x+24y=48
24y=48
divide both sides by 24
y=2
sub back
2x+9y=24
2x+9(2)=24
2x+18=24
minus 18 both sides
2x=6
divide 2
x=3
x=3
y=2
(x,y)
(3,2)
=3
The absolute value of any number is ALWAYS positive. Negatives get changed to positives.
5-2=3
Answer:
x < -10.5
Step-by-step explanation:
list the integers that satisfy both these inequalities, 2x+9 <-12
Subtract 9 from both sides;
2x +9 - 9 < -12-9
2x < -21
x < -21/2
x < -10.5
<em>Hence all the integers are values of x less than 10.5</em>
