The sum of the ages of a boy and his mother is 48. If the mother is three more than twice the boy’s age, find the difference in the ages of the boy and his mother.
Answer:
18 years
Step-by-step explanation:
let the boy's age my x and mother's age be y
x+y=48
y=3+2x which can also be written as 2x-y=-3
on solving both the equations,
you will get x=15 and y=33
so son's age is 15 years and mom's age is 33 years and the difference between their ages is 18

HELP LOLL
Answer:
RT=108
Step-by-step explanation:
Consider ΔQST:
Use pythagorus's theorem.
a²=b²+c²
QS²=QT²+ST²
53²=QT²+28²
2809-784=QT²
QT=√2025=45
Consider ΔQRT:
Use pythagorus's theorem.
a²=b²+c²
QR²=QT²+RT²
117²=45²+RT²
13689-2025=RT²
RT=√11664=108

Matthew invested $5,300 in an account paying an interest rate of 2.1% compounded annually. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $6,020?
Answer: it would be 6
Step-by-step explanation
Delta math
Based on the information for the value of the account to reach $6,020? given it will take 6 years.
Value of account:Let x represent the number of years
(2.1%×5,300)x+5,300=6,020
111.3x+5,300=6,020
Collect like terms
111.3x=6,020-5,300
111.3x=720
Divide both side by 111.3x
x=720/111.3
x=6 years

Row 2: 541
Row 3: 637

349 + 4.80n
3
135
Step-by-step explanation:
1
For this, use the equation I gave you above to find the costs.
2
First, the cost of the printer will NOT change, for the number of printers Eddie needs to buy does not change, he only needs one. This already helps you figure out that 349 is not a coefficient to the variable, n. However, when it comes to the number of blank shirts Eddie needs to buy, the number of he gets does change, this is the dependent variable that makes the cost vary. Using the equation above, you can plug in any number.
For example, 20.
349 + 4.80(20) = 445
3
For this final part, I just kept using the equation until I got the closest number that is lower than 1000. In this case, 135 got me 997, and 136 was just a few decimals away from 1000, but it was still over.

the base of a triangular field is 22m. The area of the field is 550m2 . find the height
Step-by-step explanation:
Area of triangular prism =1/2 ×base×height
550=1/2×22×h
h=550/11
h=50m
hope it helps.
Answer:
height = 50 m
Step-by-step explanation:
Area of a triangle = 1/2* base * height
550 = 1/2 * 22 * height
550 = 11 * height
therefore, 550/11 = height
therefore, height = 50 metres

Suzy is competing in a 651 mile long-distance bicycle race. In the first 3 and 1/2 hours she completed 54 and 1/4 miles. If she plans to ride 7 hours per day, how many days will it take for her to complete the race at that pace?
Answer: 6 days
Step-by-step explanation:
1. Multiply 54 1/4 by 2 (We are multiplying my 2 because 3 1/2 hours is half of 7 hours, so you have to multiply to see how much Suzy rode for 7 hours.
2. Now, divide 651 by the answer you get in step 1 to get your answer (simplify if necessary.)
=> 54 1/4 * 2 = 108 1/2
=> 651 / 108 1/2 = 6
