Answer:
14. d
15. b
Step-by-step explanation:
steps for #14:
1. complementary angles are angles that equal 90 degrees when added together. so, those two angles equal 90. make an equation to represent this.
(x + 5) + (x - 9) = 90
2. combine like terms.
2x - 4 = 90
3. solve for x.
2x = 94
x = 47
4. plug x into both formulas to find the measurements of each angle.
47 + 5 AND 47 - 9
d. angle DFG = 52, angle JKL = 38
steps for #15:
1. when angles are linear pairs, it means they equal 180 degrees when added together. so, these two angles equal 180. make an equation to represent this.
(x - 39) + (x + 61) = 180
2. combine like terms.
2x + 22 = 180
3. solve for x.
2x = 158
x = 79
4. plug x into both formulas to find the measurements of each angle.
79 - 39 AND 79 + 61
b. angle 1 = 40, angle 2 = 140

A taxi cab company charges a flat amount of $5.00 plus a rate of $3.00 per mile traveled, what is the total number of miles traveled if the fare was $41.00
Answer:
Step-by-step explanation:
Amount charged = $5.00
Amount charged for per mile = $3.00
Miles traveled =
Total amount charged = $41.00
Total amount = $3 per mile - $5
41-5 = 35
Miles traveled= $35 ÷ $3
35÷3 = 11.66
Miles traveled = 11/11.66

The area of a square ice rink is 400 yd.². What is the perimeter of the rink in yards
Answer:
80 yd^2
Step-by-step explanation:
Since the formula for squares is s^2, we can use this to set up an equation, which is
s^2=400
If we square root this, we get
s=20
The perimeter formula for a square is 4s, so if we plug in, we end up with 80 yd^2

kelly is going to buy 12 items from Pablo's Food Truck. 1/6 of the items are tacos, 25% are empanadas, 1/3 are tamales and the rest are burritos. How many burritos did kelly buy?
Answer: 3 burritos
Step-by-step explanation:
Fraction of tacos = 1/6
Fraction of empanadas = 25% = 1/4
Fraction of tamales = 1/3
Fraction of burritos = 1 - (1/6 + 1/4 + 1/3)
It should be noted that the lowest common multiple for 6, 4 and 3 is 12.
Fraction of burritos = 1 - (1/6 + 1/4 + 1/3)
= 1 - (2/12 + 3/12 + 4/12)
= 1 - 9/12
= 3/12 or 1/4
The number of burritos bought by Kelly will now be:
= 1/4 × 12
= 3 burritos

A x − 3y + 8z
B 2x − 2y + 8z
C 3y + 8z
D−3y + 8z
Answer:
D) -3y + 8z
Step-by-step explanation:
2x - 2y + 5z - 2x - y + 3z
first, group the same variables together.
2x - 2x - 2y - y + 5z + 3z
then, this step which I don't have a name for.
2x - 2x = 0x.
-2y - y = -3y
5z + 3z = 8z
0x - 3y + 8z
or, -3y + 8z

A bag with quarters and nickels contains 87 coins.The total amount is $7.35. How many quarter and nickels are in the bag
Answer: 72 nickels and 15 quarters
Step-by-step explanation:
72 times .05 = 3.6 or $3.60
15 times .25 = $3.75
Total = $7.35
.05 is representing the nickels and .25 is representing the quarters and if you take a calculator and do 87-72 you get 15 and you can set it up yourself to double check. But I wouldn't recommend doing it with pennies that's how I got confused so many times and you can also give yourself a similar problem if you want to make sure you know how to do it. Sorry if this was confusing.

round 2.52 to the nearest tenth
Answer:
2.5
Step-by-step explanation:
Answer:
2.50
Step-by-step explanation:
the tenths place is right after the ones place and before the hundreths place.
in 2.52, 5 is in the tenth's place. It's value is 5/10. The number in the hundreths place is 2, 2 is less than 5 so we round down. 2.52 becomes 2.50
Nathalie has some quarters, dimes, and nickels. The ratio of the number of quarters to the number of dimes to the number of nickels that she has is $9:3:1$. The total value of these coins is $18.20. How many coins does Nathalie have?
Answer:
the answer is 91
Step-by-step explanation:
One group of 9 quarters, 3 dimes, and 1 nickel has the value of $9 \times 25 + 3 times 10 + 5=26 cents or 2.60 in total.
Since the coins she has are in this same ratio 9:3:1, we can split her coins up into groups of 9 quarters, 3 dimes, and 1 nickel, with each group having a value of 2.60
Because the total value of her coins is 18.20and 18.20\2.60=7, she has 7 of these groups of coins.
Each of these group contains 13 coins, so she has 7 times 13 = 91 coins in total.
Each of these group contains 13 coins, so she has total 91 coins.
What are nickles, dimes, quarters and cents?A dollar is further divided into some majorly used parts as:
A cent = 100th part of a dollar = $1/100 = $0.01
A nickle= 20th part of a dollar = $1/20 = $0.05
A dime = 10th part of a dollar = $1/10 = $0.10
A quarter = 4th part of a dollar = $1/4 = $0.25
One group of nine quarters, 3 dimes, and 1 nickel has the value of $9
25 + 3 times 10 + 5=26 cents or 2.60 in total.
Since the coins Nathalie has are in this same ratio 9:3:1, thus we can split her coins up into groups of 9 quarters, 3 dimes, and 1 nickel, with each group having a value of 2.60
Due to the total value of her coins is 18.20
18.20/2.60=7,
Hence, she has 7 of these groups of coins.
Each of these group contains 13 coins, so she has total ;
7 x 13 = 91 coins

A group of 5 people planned to spend $12 each to rent power tools to build playground equipment for a day camp. At the last minute, 1 person
could not participate. If the others then paid equally for the tools, how much did each pay?
Answer:
The answer would be 48 since it would be 4 x 12
Answer:
$15
Step-by-step explanation:
If the 5 people where each paying $12 to rent the equipment, that means the cost of the equipment can be found multiplying 5 and 12 to get 60. Now that we know that the cost of the equipment is $60, if one person bailed out, there are now 4 people to rent it. You can find how much each person pays if they each pay the same amount by dividing 60 by 4. Once you do $60 ÷ 4 people = 15. So each person pays $15.
I hope this helps :)
HELP PLEASE ITS DUE IN 10 MIN Use algebraic strategies to solve for x.
Check your solutions algebraically and identify any extraneous solutions. Write it step by step.
Answer:
x = 4, x ≠ -1
Step-by-step explanation:
√3x + 4 = x
(√3x + 4)² = x² (Square both sides to get rid of the radical.)
3x + 4 = x²
0 = x² - 3x - 4 (Set everything to 0 by moving everything to one side.)
0 = (x - 4)(x + 1) (Factor.)
x = 4 x = -1
Now we need to check for extraneous solutions:
√3(4) + 4 = 4
√12 + 4 = 4
√16 = 4
4 = 4
√3(-1) + 4 = -1
√-3 +4 = -1
√1 = -1
1 ≠ -1
-1 is an extraneous solution.
