How do I solve for x
Answer:
1. x = 3
2. x = 8
3. x = 5
4. x = 8
Step-by-step explanation:
1. 18 = 6x
divide both sides by 6
x = 3
2. x + 7= 15
subtract 7 from both sides
x = 8
3. 2x - 2 = 8
add 2 to both sides
2x = 10
divide 10 by 2
x = 5
4. -1 + x = 7
add 1 to both sides
x = 8
Can someone please explain this to me? I’d be so appreciative.

If t= 9m,what is the area of the triangle
Help
Answer: the answer
we use the formula 1/2 .b .h
Step-by-step explanation:
the answer is 1,134, we substitute the t to 9 for each number, for example 4(9) 7(9)
4(9)= 36
7(9)=63
now we find the half of our bottom number which is 4=36
1/2 36= 18
so now we have 18x63=1,134
so our answer is 1,134
The area of the triangle is 1134 m²
What is the area of Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
Given data ,
The value of t = 9 m
Let the base of the triangle be b = 4t
= 4 x 9
= 36 m
Let the height of the triangle be h = 7t
= 7 x 9
= 63 m
Now , the area of the triangle = ( 1/2 ) x Length x Base
So , substituting the values , we get
Area of the Triangle = ( 1/2 ) x 36 x 63
= 18 x 63 m²
= 1134 m²
Therefore , the area is 1134 m²
Hence , the area of the triangle is 1134 m²

A ladder is 8 meters long. It leans against a wall with one end on the ground, 6 meters from the wall. The other end reaches a windowsill. Calculate the height of the window sill above the ground.
Answer:
[tex]\sqrt{28[/tex]
Step-by-step explanation:
a^2 + b^2 = c^2.
if you draw out the triangle, you can substitute numbers into an equation.
6^2 + b^2 = 8^2
36 + b^2 = 64
b^2 = 64 - 36
b^2 = 28
b = [tex]\sqrt{28}[/tex]

since same equation, they are same line and lines are infinite so infinite solutions is answe
Answer:
No solution
Step-by-step explanation:
PEMDAS = distribute first.

The school that Anthony goes to is selling tickets for a choir concert. On the first day of ticket sales his school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. What is the price of a senior citizen ticket?
Answer:
A senior citizen costs $8
Step-by-step explanation:
Represent senior citizens with S and children with C.
The first day is represented as:
[tex]3S + C = 38[/tex]
The second day is represented as:
[tex]3S + 2C = 52[/tex]
Required
Solve for C and S
Make C the subject in the first equation
[tex]C = 38 - 3S[/tex]
Substitute 38 - 3S for C in the second equation
[tex]3S + 2(38 - 3S) = 52[/tex]
[tex]3S + 76 - 6S = 52[/tex]
Collect Like Terms
[tex]3S - 6S = 52 - 76[/tex]
[tex]- 3S = -24[/tex]
Divide through by -3
[tex]S = 8[/tex]
Recall that: [tex]C = 38 - 3S[/tex]
[tex]C = 38 - 3 * 8[/tex]
[tex]C = 38 - 24[/tex]
[tex]C = 14[/tex]
Hence, a senior citizen costs $8

Step-by-step explanation:
It is C because I can plot all those points and they are still on the blue line. If you don't believe me, plug them in to y=-3/2x+2, (-4,8 plugged in would look like this 8=-3/2(-4)+2 just plug the x and y coordinates in) and they will be correct.
Hope this helps plz hit the crown:D
Answer:
B
X can be any real number, there are a lot of solutions for y = -3/2x+2 so the answer is not C or D
for a given x,y can only be y=-3/2*x+2 not any value y so the answer is not A
Since for a given x,y can only be y=-3/2*x+2 the solutions will be ~x,y = -3/2*x+2) or ~x, -3/2*x+2~ for all real numbers

Range is the set of y-values that are outputted by function f(x)Step-by-step explanation:
From the graph we see that our y-values span from -4 to 4. When y = -4, it is a open dot, meaning it is exclusive. When y = 4, it is a closed dot, meaning it is inclusive. Therefore, our range is:
(-4, 4] or -4 < y ≤ 4

Thirteen candy bars weigh 26 ounces what is the weight of 35 candy bars
Answer:
70 ounces
Step-by-step explanation:
We can solve the weight of 35 candy bars by first finding the weight of one and multiplying by 35.
If 13 candy bars each weigh 26 ounces, one will weigh 2. We can write this out as shown:
13x = 26
x = 2
Now we simply multiply by 35 to get the total weight of 35 candy bars:
35x = 35(2) = 70
Number 21 plsss helppppp
Answer:
B
Step-by-step explanation:
First off, we see that x ≥ -2. That little horizontal line right under the > sign indicates that x is "greater than or equal to" -2. Because we want to include -2 in the solution set, the dot on the number line at -2 should be shaded in.
This already eliminates A and D.
Now, we're left to choose between B and C.
Well, we know that x is greater than or equal to -2, so possible values of x should be numbers that are more positive than -2, or that point in the positive direction. That's exactly what B illustrates, so that's our answer.
