If the perimeter is 20 what must be the length of the missing side length? (Answer with Number Only) *
Answers
Answer:
8
Step-by-step explanation:
Perimeter = Sum of all side lengths
If perimeter = 20, then 5 + 3 + 4 + x = 20
( where x = missing side length )
5 + 3 + 4 = 12
12 + x = 20
20 - 12 = 8
Hence, x = 8
Step by step
5+3= 8
8+4=12
20-12=8

A rock climber ascends 18 3/4 feet to the top of a rock ledge. He descends 8 1/8 feet and takes a break on a rock outcrop. Write and then evaluate an addition expression to show how much further the rock climber must descend to reach his original level. Enter the correct answers in the boxes.
Answers
Answer:
3
Step-by-step explanation:
The rock climber must descend 10 5/8 feet to reach his original level.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
To evaluate this expression, we first need to convert the mixed numbers to fractions. 18 3/4 is equal to 18 + 3/4 = (72+ 3)/4 = 75/4.
Similarly, 8 1/8 is equal to 8 + 1/8 = (64 + 1)/8 = 65/8.
So, the rock climber must descend :
= 75/4 - 65/8
= (75x8 - 65x4)/(48)
= (600 - 260)/32
= 340/32
= 10 5/8 feet to reach his original level.
Thus, to ascend to his original level, the rock climber must descend 10 5/8 feet.

Charlie bought pound of American cheese and pound of Swiss cheese. Josh bought pound of cheddar cheese and pound of jack cheese. Josh says that they bought the same amount of cheese. Is he correct? Explain.
Answers
Answer: It is not possible to determine whether Josh is correct without more information. In order to determine whether they bought the same amount of cheese, it would be necessary to know the weight of the cheeses that Charlie and Josh bought. If the weight of the cheeses that Josh bought is equal to the weight of the cheeses that Charlie bought, then Josh is correct and they did buy the same amount of cheese. However, if the weight of the cheeses that Josh bought is not equal to the weight of the cheeses that Charlie bought, then Josh is incorrect, and they did not buy the same amount of cheese.
Step-by-step explanation: It's hard to say because you would need the weight of the cheese.

Hazel is putting together charm bracelets. For each bracelet 1/5 of a yard of string and 12 charms. hazel has 5/8 of a yard of string and 96 charms. she makes the charm bracelet until all of the string is gone. what fraction of charms did she use?
Answers
Answer:
3/8
Step-by-step explanation:
First, find the number of bracelets she's able to make with her string. She has 5/8 of a yard and uses 1/5 per bracelet. To divide the number of yards she has by the number she uses, multiply 5/8 by the reciprocal of 1/5 (5/1).
5/8 * 5/1 = 25/8
25/8 is 3.12500, which is the number of bracelets she can make. It rounds down to 3 since she can't make 0.12500 bracelets.
Now, find how many charms she used. 3 bracelets * 12 charms each is 36 charms in total.
So she used 36/96 of her charms. This can be simplified to 3/8.
Answer:
37/96 hazel has
Step-by-step explanation:
1/5 times 12=60
so Hazel uses 1 yardd for 60 charms, so for 5/8 yard Hazel would use 5/8×60=37.5.
since Hazel isn't able to use a fraction of a charm, she would use 37 charms
37/96 Charms Hazel has

y=19°{ vertically opposite angle r equal}
y+z=90° {given in questions.}z=90-19z=71°
hope it helps.
stay safe healthy and happy.Answer and Step-by-step explanation:
1.
I see the Vertical Angles Theorem being used with the angle of 19 and angle y.
Vertical Angles Theorem states that angles that are vertical to each other are congruent to each other.
I see the Complementary Angles Theorem being used with the angle y and angle z.
Complementary Angles Theorem states that angles that are next to each other and are split by a line of a right angle will add up to 90 degrees.
2.
y = 19
y + z = 90
Substitute 19 for y.
19 + z = 90
Subtract 19 from both sides of the equation.
z = 71
