7/8 and 3/4 
Both need to have same denominator so it would be 32, in this case because 8*4 is 32. 
7/32+3/32=10/32 simplified to 5/16

The height of a triangle is 6 m more than its base. The area of the triangle is 56 m?. What is the length of the base? Enter you
Marizza181 [45]

Answer:

Height = 14

Base = 8

Step-by-step explanation:

h=6+b

a=(1/2)bh

a=56

56=(1/2)bh

times 2 both sides

112=bh

h=6+b

112=b(6+b)

112=b²+6b

minus 112 both sides

0=b²+6b-112

factor

what 2 numbers multily to get -112 and

add to get 6

-8 and 14

0=(b-8)(b+14)

set to zero

b-8=0

b=8

b+14=0

b=-14

false, measures can't be negative

base=8

h=6+b

h=6+8

h=14

height=14

base=8

Solve for x. 2 1/2x − 3/4 (2x+5) = 38 ASAP
svetoff [14.1K]

Answer:

  x = 41 3/4

Step-by-step explanation:

(2 1/2)x -(3/4)(2x +5) = 38

(2 1/2)x -(1 1/2)x -15/4 = 38 . . . . use the distributive property

x = 38 +3 3/4 . . . . . . add 15/4

x = 41 3/4

_____

Another way to solve this is to "clear fractions" by multiplying the whole equation by 4:

  10x -3(2x +5) = 152

  4x -15 = 152 . . . . eliminate parentheses

  4x = 167 . . . . . . . add 15

  x = 41 3/4 . . . . . . divide by 4

George traveled 300 miles in 8 hours. How far could he travel in 4 hours if he traveled at the same rate?
Amiraneli [1.4K]
Divide 300 by 8 to find the unit rate
300/8= 37.5

He travels 37.5 miles per hour

If he travels 37.5 miles per hour, to find the amount in 4 hours we would do 37.5 times 4


37.5×4=150


In 4 hours he travels 150 miles
