Answer:
5m-50
Step-by-step explanation:
Let Diego current age be x,
Given that Diego’s current age is five times Martina’s age ten years ago
Martina current age = m years
10 years ago Martina's age = m-10
Hence we have
x = 5(m-10) = 5m-50
So we find that Diego's current age can be expressed in terms of m as
Deigo's current age= 5m-50
Verify:
Deigo current age = 5m-50
Hence Martina age 10 years ago = 5m-50 divided by 5 = m-10
Martina current age = m-10+10 = m
Verified.
Answer:
117.65%
Step-by-step explanation:
make the assumption that 646 is 100% since it is our output value.
step 2. we next represent the value we seek with x.
step 3 . from step 1 , it follows that 100%=646
step 4. in the same vein, x%=760
step 6. this gives us our pair of equations 100%=646(1)
x%=760(2)
step 6. by simply dividing equation 2 and by taking note of the fact that both the LHS (left hand side) of both equations have the some unit (%); we have 100%=646(1) and x%=760(2)2
step 7. taking the inverse (or reciprocal) of both sides yields 100%/x% = 646/760
= 117.65%
therefore , 760 is 117.65% of 646.
