Answer:

104

Step-by-step explanation:

Based on the total amount spent, we can infer that the number of nails Marta purchased was 74 nails.

Marta purchased 15 screws which cost $0.10 each. The cost is therefore:

= 15 x 0.10

= $1.50

The amount spent on nails is:

= 5.20 - 1.50

= $3.70

If each nail cost $0.05, the total nails bought is:

= 3.70 / 0.05

= 74 nails

In conclusion, 74 nails were purchased.

Reasoning: Complementary angles always add to 90 degrees.

If angle 2 was x, then x+83 = 90 solves to x = 7

The measure of m∠2 is 7° due to the pair of angles being complementary.

The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles. There are two types of supplementary angles.

Adjacent angles: Adjacent angles are the type of supplementary angles. Adjacent angles have a common side and vertex, for example, a corner point. Their points do not overlap in any way. In other terms, adjacent angles are pairs of two angles next to each other.

We have been given that the pair of angles as

m∠1 = 83°  and m∠2 = x

Here, the pairing of angles sums up to 90° then they are called complementary angles.

So x + 83 = 90°

⇒ x = 90° - 83°

⇒ x = 7°

Therefore, the value of m∠2 is 7°.

You should go with the 1st, because it's cheaper.

Step-by-step explanation:

1st plan:

30$ which include 75 mins of free calls and 100 free text messages

25 more mins * 10¢ /min(0.1$/min) = 2.5$

You will pay 32.5$

2nd plan:

(calls)100*0.3$=30$

(text messages)100 * 0.1$=10$

30+10 = 40$

Answer:

Brianna subtracted $12.50, even though you are not supposed to do that to find the price. You have to subtract $6.50, not $12.50.

The final answer is $7.04 because you subtract two initial prices.

Hope this helps you!

Answer:

The sample answer is :Brianna took both 25% discounts off the original amount. The second discount should have been calculated on the first reduced price of $9.38. The final sale price should have been $7.03.

Answer:

129:175

Step-by-step explanation:

Andy and Christopher are measuring a liquid solution using a graduated cylinder

Andy uses 3.5 liters of the liquid solution

3.5 liters to mililiters

= 3.5 ×1000

= 3500 mililiters

Christopher uses 2580 mililiters

Therefore the ratio of Christopher's measurement to Andy's measurement can be calculated as follows

= 2580/3500

= 129 : 175

Hence the ratio of Christopher's measurement to Andy's measurement is 129:175

Answer:

first problem) he messed up at 4(1 + 5n), only multiplying the 1 by 4, instead of both the 1 and 5n,

work-

-8n + 4(1 + 5n) = -6n - 14

-8n + 4 + 20n = -6n -14

12n + 4 = -6n - 14

18n +4 = -14

18n = -18

n= -1

second problem)  he messed up towards the end, where he put 3x = 3x, then x=0. in this case, x would equal x, so the answer is "infinitely many solutions"

all the other work is correct in that problem

third problem) on the right side of the equation, ( 4x+10+3x-6), when they were adding the like numbers, instead of subtracting 6 from 10, they added 6, giving them 16 instead of 4

correct work-

2x - 8 + 3x +2 = 4x +10 + 3x -6

5x - 6 = 7x + 4

-5x         -5x

-6 = 2x +4

-4           -4

-10 = 2x

-5 = x

Answer:

I believe it would be A: 60°.

Step-by-step explanation:

I suck at explaining stuff but since R is 60°, and theres 120° outside of the triangle, that implies T = 60°. Triangles equal 180° so

60° + 60° + S = 180°

S = 60°

Hope this helps

Answer:

The answer of the question is 60° which is option(A).

here,

let one be suppose angle a°

a°+ 120° = 180° {being straight angle}or, a° = 180° - 120°

or, a° = 60°

a° = 60°

Now,

Let angle S be s°

s°+60°+60° = 180°{ the sum of angle of triangle is 180°}

or, s° = 180° - 120°

or, s° = 60°

therefore, angle S is 60°

Answer:

x = -8

Step-by-step explanation:

3(x+1)+11=-2(x+13)

3x+3+11=-2x-26

3x+14=-2x-26

5x=-40

x=-8

Answer:

x = -8

Step-by-step explanation:

Step 1: Write equation

3(x + 1) + 11 = -2(x + 13)

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

3(-8 + 1) + 11 = -2(-8 + 13)

3(-7) + 11 = -2(5)

-21 + 11 = -10

-10 = -10
