Answer:
Maggie is 6 years old
Step-by-step explanation:
M + B = 26
B = 26 - M
4M - 4 = B
4M - 4 = 26 - M
5M = 30
M = 6

Answer: 32 cups of milk
Step-by-step explanation:
The first thing to do is to convert the gallons of milk to milkshakes so that you are able to convert easier to cups.
There are 128 ounces in 1 gallon and Monica has 2 gallons. The amount of milk Monica has in ounces is:
= 128 * 2
= 256 ounces
Each cup is capable of holding 8 ounces and there are 256 ounces available so the number of cups of milk is:
= 256 / 8
= 32 cups of milk
Answer:
105
Step-by-step explanation:
because you multiply 5 times 3 which is 15 times 7 equals 105
Answer:
1.42 pages
Step-by-step explanation:
10/7= 1.42 that'd be the pages per second
Dennis = 12 km'h
Kathy = 20 km/h
Step-by-step explanation:
- Lets first establish that time is the same for both Kathy and Dennis and we can therefore assign is the value of <em>t</em>
- Kathy is cycling 8km/h faster than Dennis. Therefore if Dennis is doing <em>x </em>km/h Kathy is doing (<em>x</em>+8)km/h
- If it takes Kathy<em> t </em>time to cycle for 60 km at (<em>x</em>+8)km/h, we can derive the time <em>t </em>as;
(<em>x</em>+8)* <em>t </em>= 60
<em>t</em> = 60/(<em>x</em>+8)
- We can now use this time to establsish how fast Dennis is cycling. Dennis, using a speed of <em>x</em> km/h takes the same time (60/(<em>x</em>+8)) to cycle for 36 km. Therefore;
<em>x</em> * 60/(x+8) = 36
= 60x/(x+8) = 36
36 (x + 8) = 60x
36x + 288 = 60x
288 = 60x – 36x
288 = 24x
12 =<em> x </em>
Dennis is cycling at 12 km/h
Kathy is doing x + 8
= 12 + 8 = 20 km/h
