x°+(x+30)=180°
I need answer
Answer:
210 + -1x
Step-by-step explanation:
Simplifying
X + (x + -30) = 180
Reorder the terms:
X + (-30 + x) = 180
Remove parenthesis around (-30 + x)
X + -30 + x = 180
Reorder the terms:
-30 + X + x = 180
Solving
-30 + X + x = 180
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '30' to each side of the equation.
-30 + X + 30 + x = 180 + 30
Reorder the terms:
-30 + 30 + X + x = 180 + 30
Combine like terms: -30 + 30 = 0
0 + X + x = 180 + 30
X + x = 180 + 30
Combine like terms: 180 + 30 = 210
X + x = 210
Add '-1x' to each side of the equation.
X + x + -1x = 210 + -1x
Combine like terms: x + -1x = 0
X + 0 = 210 + -1x
X = 210 + -1x
Simplifying
X = 210 + -1x
9. Gregory's nine chickens laid an average of six eggs each per week. Gregory sold those eggs for $300 per dozen. How much money did he collect in two weeks if he sold all his eggs??
Step-by-step explanation:
Average in one week 6eggs
2 weeks 12 eggs
1 dozen =12 eggs
1 dozen =300 dollars
2*300=600 ans
Answer:
$2,700
Step-by-step explanation:
The first thing we should do is to find the number of eggs in two weeks.
6 eggs each for 9 chickens which means:
6 * 9 = 54
54 eggs per week.
In two weeks,
54 * 2 = 108
108 eggs for two weeks
Now a dozen is equivalent to 12 eggs. So if you divide 108 to 12:
108 ÷ 12 = 9
So it is 9 dozens. Then he's selling those eggs for $300 per dozen.
300 * 9 = $2,700
That's it.
5.) Which is the best deal? *
$25 for 5 pizzas
$32.48 for 7 pizza
$27.45 for 3 pizzas
$28.74 for 4 pizzas
Answer:
$27.45 for 3 pizzas
In my opinion
Answer:
$32.48 for 7 pizzas
Step-by-step explanation:
25 divided by 5 = $5
32.48 divided by 7 = $4.64
27.45 divided by 3 = $9.15
28.74 divided by 4 = $7.185
Solve the linear systems using multiplication 6x - 12y = 15;2x - 4y = 6 -
Answer:
your answer would be 1
Step-by-step explanation:
The whole equation is divided by 3 to get 2x-4y=5, but since there is a 6 we need to subtract 1 away to get 5.
The water park is a popular field trip destination this year the senior class at High School A and a senior class at High School B both planned trips there. The senior class at High School A rented and filled 10 vans and six buses with 220 students. High School B rented and filled 11 vans and 12 buses with 350 students. Every van had the same number of students in it as did the buses. Find the number of students in each vans and each bus.

Sprinters who run 100 yards now often run 100 meters.
How many meters longer to the nearest tenth is 100 meters than 100 yards?
Enter the correct answer in the box.
Answer:
100 meters is 8.6 meters longer than 100 yards.
Step-by-step explanation:
Conversion of yards to meters.
Each yard has 0.914 meters.
So 100 yards is 100*0.9144 = 91.4 meters.
How many meters longer to the nearest tenth is 100 meters than 100 yards?
100 yards = 91.4 meters
100 - 91.4 = 8.6
So 100 meters is 8.6 meters longer than 100 yards.

The price of a computer was decreased by 30% to £147.
What was the price before the decrease?The price of a ring was increased by 9% to £1800. What was the price before the increase? Give your answer to the nearest penny.
Answer:
a) £210
b) £1651.38
Step-by-step explanation:
a)After the reduction, the price is 1 -30% = 0.70 of what it was.
0.7p = £147
p = £147/0.7 = £2.10 . . . price before decrease
__
b)After the increase, the price is 1 +9% = 1.09 of what it was.
p = £1800/1.09 ≈ £1651.38 . . . price before increase

Answer:
Ms. Brown needs 0.18 more cents to afford the pounds of granola and cranberry mix.
Step-by-step explanation:
Ms. Brown = $10 limit
Purchases 1.75 lbs of granola and 2.9 lbs of cranberry mix
Cranberry per lb = $3.25
Granola per lb = $2.19
1.75 x 2.19 = 3.8325 (Cost of granola)
2.9 x 2.19 = 6.351 (Cost of cranberry)
3.8325 + 6.351 = 10.1835 (Total cost of both cranberry and granola)
10.1835 rounded to nearest cent = 10.18
10 < 10.18
Ms. Brown doesn't have enough money to buy the pounds of granola and cranberry mix.
What is the value of y?
09
O 18
O 3
Answer:
The answer is 9
Step-by-step explanation:
First looking at the triangle with the 90 degree sign in it we know that the other angles in that triangle will have to add with 90 to equal 180
So doing the easier way replace 9 with y and do this for the other numbers 3 and 18 to see if the result of (2y+18) and 4y will equal the same number
[tex](2(9)+18)=36 \\4(9)=36[/tex]
[tex](2(3)+18)=24 \\4(3)=12[/tex]
[tex](2(18)+18)=54 \\4(18)=72[/tex]
and because the lines on each triangle represent that those sides are congruent
I hope this because I am only using what I remember from geometry but please let me know if I am wrong

Compared to last year, the population has increased 25%. The population is now 6,600. What was the population last year?
What number of population do I put for each for percentage?
Answer:
4,950
Step-by-step explanation:
:)
1,650-25% 3,300-50% 4,950-75% 5,280-100%
Step-by-step explanation:
convert the percentage to a decimal then multiply by 6,600. To get the number of people of 100%, divide 1.25 (the percent of 6,600) by 6,600. That should be right,
