Hello!
You first cross multiply
4 * 7 = 28
5 * r = 5 * r
r * 5 = 28
Divide both sides by 5
r = 28/5 = 5.6
The answer is 28/5 or 5.6
Hope this helps!
Answer:
a= -12 and b=36
Step-by-step explanation:
a+b=24 and 3a+b
a-3a+b=24
-2a+b-b=24
-2a/-2=24/-2
a= -12
then substitute the value of a in a+b=24 to get the value of b
so let see -12+b=24
b=24+12
b=36
we can check it by the equation -2a+b-b=24
-2(-12)+36-36=24
24=24 so as you have seen the answer is correct
thanks!!!
Answer:
less than 2,000 times wider
Step-by-step explanation:
2 x 10 x 7 = 7 x 10 x 2 = 10 x 2 x 7 = 7 x 2 x 10
Answer:
It is required to draw a number line showing equivalent fractions.
'Equivalent fractions' are the fractions having same value even though the digits involved are different'.
For example: Consider,
and
.
Now, we have,
= 0.5
= 0.5
Thus, the both fractions have the same value, even though we are dividing different digits.
Thus,
and
are called equivalent fractions.
So, we plot them on the number line, resulting in the following figure with point P = 0.5.
