Answer: substitution
Step-by-step explanation:
Substitute 3 in for x for all equations.
3(3)+4 = 13
8(3)-1 = 23
3(3)+4 =13
Add all of the sides together to find the perimeter
13+23+13 =49

option B
Answer:
B. Sin A = [tex]\frac{4}{5}[/tex]
Step-by-step explanation:
Sin A = opposite / hypotenuse
Sin A = 28 / 35
Divide both by 7
28 / 7 = 4
35 / 7 = 5
[tex]\frac{28}{35} = \frac{4}{5}[/tex]

3. The sum of two numbers is 17. The difference between the larger number and the
smaller number is 7. What is the value of the smaller number?
Answers
Answer:
5
Step-by-step explanation:
To solve this problem, we need to set up a system of equations. Let x represent the larger number and y represent the smaller number.
x + y = 17
x - y = 7
We can solve this system by adding them together. The y cancels out because y + (-y) = 0. After that, we solve for x
2x = 24
x = 12 (Divide both sides by 2)
Now that we know the value of x, we can substitute it into one of our original equations to solve for y.
12 + y = 17
y = 5 (Subtract 12 from both sides)
So, the smaller number is 5.

Find it ! Find the perimeter
Answers
Answer:
P=60
Step-by-step explanation:
P=2(l+w)
P=2(14+16)
P=2(30)
P=60
Perimeter of a rectangle with 16in length and 14in width is 60 in.
Perimeter of a rectangle = 2(l+b)
here l = length and b= width
Given : l= 16 in and b= 14 in
perimeter = 2(l+b)
= 2(16+14)
= 2(30)
=60 inches.
The perimeter of rectangle is 60 inches

In right triangle angles L and M are complementary find the measure of angle L
Answers
Answer and Step-by-step explanation:
90 - 51 = 39.
Angle L is equal to 39, since angle M is equal to 51.
The angles are complementary, so they add up to 90, which is why we subtract 51 from 90 to get 39.

I have and a math test in an hour and a half. It’s about algebraic word problems. Can someone help me. I’m really struggling in maths
Answers
First of all, relax and take a deep breath right before you start.
Alright, so algebraic word problems are tricky sometimes. I am glad I don’t have to do them much. Once you understand more or less what to do, you should be fine!
I would need an example problem if you have one.
If not, then remember that you have to work with what you know, which is what you can start with and what you need to end with.
For instance, a phone company sells phones at $900 each. For a family discount, after 2 phones are bought, each additional phone is $100 off.
Find an expression representing the phone company’s prices.
2*900 + (900x - 100x)
x represents how many additional phones were bought.
If a family bought 6 phones:
2*900 + (900x - 100x)
2 in front and 4 as x gives 6
That expression becomes
2*900 + [900(4) - 100(4)]
= $5000

Cheapstore= 600g 20% off the normal price of £5 Superstore= 600g plus extra 30% extra £5 which box of ceral has better value?
Answers
Answer:
The one from superstore
Step-by-step explanation:
We are to find the box if cereal that gives us the best value for our money.
We first calculate for cheapstore
We have 500 pounds divide through by 10 = 50p
Multiply 50 with 2
= 100p
= 1 pound
4 pounds = 600 grams
For superstore
Divide 600 g by 10
= 60g
Multiply with 3
= 60g x 3
= 180g
600+180 = 780grams
600grams/4pounds = 150g
780grams / 5 pounds = 156gtams
From here we concise that superstore box has best value

To pay for the trip, friends work in the local shop. Each of them is paid $5 per hour. If each friend works the same number of hours, how many hours must each friend work so that there will be enough money to pay for the entire cost of the trip?
Answer this pls I'm this accounts cousin help me
Answers
Answer:
Step-by-step explanation:
Okay so first you need to find out how much money it will cost in total.
$50*5
=$250
$250+$850=
$1,100
Now, $1,100 divided by 5
1,100/5
=220 hours
And there are 5 friends so divide the total amount hours by 5.
220/5
=44 hours
So you see, each friend will need to work 44 hours.
