1. Erwin hiked 5/7 of a kilometer while
Jericho hiked 2/3 of a kilometer. How many
kilometers did they hiked in all?
Asked/ Problem: How many kilometers did
they hiked in all?​

Answers

Answer 1

Answer:

the number of kilometers hiked in all is [tex]\frac{29}{21}[/tex]

Step-by-step explanation:

The computation of the number of kilometers hiked in all is shown below:

= Erwin + Jericho

[tex]= \frac{5}{7} + \frac{2}{3}\\\\= \frac{15 + 14}{21} \\\\= \frac{29}{21}[/tex]

Hence, the number of kilometers hiked in all is [tex]\frac{29}{21}[/tex]

Use the distributive property to rewrite each expression in it's equivalent form 9a-3/3 ,Just 3 please

Answers

hahahah i think i already did this for you buttttt

the denominator can be distributed to both parts of 9a and -3

so you can rewrite it as (9a/3) and (-3/3)

to simplify (9a/3) is equal to 3a and (-3/3) is equal to -1

so the answer is 3a-1

Answer:

What is the measure of angle D?

52o

Angle D = 360-128-126-54 = 52o

Step-by-step explanation: got it right on edge

Since the sum of the angles in a quadrilateral is 360 degrees then the angle D is 50 degrees.

What is a quadrilateral?

A quadrilateral is a four sided figure. Examples of quadrilaterals include; square, parallelogram, rectangle, kite etc.

The sum of angles in a quadrilateral is 360  degree hence;

A + B + C + D = 360 (sum of angles in a quadrilateral)

128 + 126 + 54 + D = 360

D = 360 - ( 128 + 126 + 54)

D = 50 degrees

NEED HELP MATH!!! 7TH GRADE

Answers

The scale drawing's measurements will be 1 inch by 0.8 inch.

The scale is 1 in: 10 feet; because the deck's real width is 10 ft, the scale can read 1 inch. To evaluate the width: 1/10 = x/8

Cross multiply:
1*8 = 10*x
8 = 10x


Divide both sides by 10:
8/10 = 10x/10
0.8 = x

The scale drawing's width would be 0.8 inches.

Bria asked her classmates whether they prefer math or science. Nine of her classmates said math and eight of her
classmates said science. Which inequality correctly compares the fraction who prefer science to the fraction who
prefer math?

Answers

Answer:

8/17<9/17

Step-by-step explanation:

Might be wrong with my answer but my logic was that if there are 9 students who prefer math and 8 who prefer science, that there are 17 students total. If there are 17 students total the denominator should be 17. Since 8 of them prefer science, we can write that as 8/17 because 8 out of the 17 students prefer science. Similarly we can write the number of students who prefer math as 9/17 because there are 9 students out of 17 who do.
