Answer:
2 7/10
Step-by-step explanation:
3/4+3/5=
Common Denominator: 20
Multiples of 4: 4, 8, 12, 16, 20
Multiples of 5: 5, 10, 15, 20
3x5=15
4x5=20
15/20
3x4=12
5x4=20
12/20
15/20+12/20= 27/20 = 2 7/10
Answer:
255
Step-by-step explanation:
4^3= 64
100/25=4
5^0=1
(64x4)-1
=256-1
=255
First you divide 23 by 5 and then what evers left you divide that by 5 until you cant divide anymore
Answer:
h=-4
Step-by-step explanation:
Use the Distributive law:
1. -3(h+5) gives us -3h-15 then you add your two(2).
the whole of your left side of the equation will give you -3h-13
2. 4(h+6) gives us 4h+24 then you subtract nine(9).
the whole of the right side of the equation will give you 4h+15
3. equate the two like this:
-3h-13=4h+15
4. group like terms of each side:
-13-15=4h+3h
5. Add and Subt<u>r</u>act
-28=7h
6. Decide both sides by 7 to make h the subject of the formula
7. Congratulations you got your answer as h=-4
