Answer:
x is 56 and y is 65
Step-by-step explanation:
If x=4 y=-3 and z =5 find the value of 5y +2x-z
Answer:-12
Step-by-step explanation:
So if the equation is 5y+2x-z and the substitutions are x=4 y=-3 z=5 , all you have to do is replace each variable with its given numbers. Like so
5(-3)+2(4)-5
Now what you have to do is simplify
Negative times a positive is a negative
Negative times a negative is a positive
Positive times a positive is a positive
So....
-15+8-5
-20+8
-12
This is a simple substitution problem. Remember the basics of negatives and positives! Than you will be just fine! :D

What method can be used to prove the triangles below are congruent
Answer:
SSS?Step-by-step explanation:
I don't know why the answers don't offer this an option. However, the side that shares both triangles must be congruent to itself and the other highlighted congruent parts are sides, not angles. Therefore by my calculations, the answer has to be SSS, but this isn't a choice.
Please let me know if you need more help :)What is the greatest common factor of 60,70, and 80
Answer:
10
Step-by-step explanation:
Answer: The GCF of 60, 70, and 80 is 10.
Step-by-step explanation: If you think about it, the GCF is definitaly going to be 10. That is because you can multiply 10 to get 60, 70, and 80. There is no other number higher than 10 that can be multiplied by something to get all of these values.

what is the sum of the interior angles of a heptagon ?
Let n be rhe number of vertices in the polygon, then the sum of all interior angle is (n - 2) × 180°.
Number of sides in a heptagon = 7
So, n = 7
So,
the sum of the interior angles of a heptagon
= (7 - 2) × 180°
= 5 × 180°
= 900°
Answer:
900
Step-by-step explanation:
Graph 8x−4y=16. From Big Ideas Math
Solve for y.
8x−4y=16
-4y = -8x + 16
y = (-8x + 16)/-4
y = (-8x)/-4 + (16/-4)
y = 2x - 4
We only need two points to graph linear equations.
Now let x be 0 and solve for y.
y = 2(0) - 4
y = -4
This leads to the point (0, -4).
We need another point.
Let y = 0 and solve for x.
0 = 2x - 4
4 = 2x
4/2 = x
2 = x
This leads to the point (2,0).
Plot these two points on the xy-plane and connect the points with a straight line.
I'll let you do that.
Understand?

Answer: -4
Step-by-step explanation:
Answer:
- 1/4
Step-by-step explanation:
The formula to find slope from two points is (x₂ - x₁) / (y₂ - y₁).
Substituting the points in (2, 4 = x₁, y₁ and 5, -8 = x₂, y₂) we get (5 - 2) / (-8 - 4).
= 3 / -12
= - 1/4
(Tip: when assigning the numbers to the variables, make sure x₁, y₁ are always from the same pair.)

what is the answer to this? −1.2b−5.3≥1.9
Answer:
b≤−6
here u go
Answer:
b ≤ -6 ✅Step-by-step explanation:
To solve an inequality, we will solve just like a normal equation. The goal is to isolate b, so we can determine the set of values it can take on.
Step 1: Add 5.3We need to reverse the operation - 5.3, so we add 5.3.
-1.2b - 5.3 + 5.3 ≥ 1.9 + 5.3
-1.2b ≥ 7.2
Step 2: Divide by -1.2We need to reverse the multiplication that is multiplying b by -1.2, so we will divide. However, we must remember an important rule first.
Important: When we divide by a negative number in an inequality, we must reverse the inequality sign, so ≥ becomes ≤.
-1.2b / -1.2 ≥ 7.2 / -1.2
b ≤ -6 (remember to reverse the sign!)
Step 3: CheckWe now substitute our answer in and see if it is correct. We will use a number that is smaller than -6, for example, -8.
-1.2(-8) - 5.3 ≥ 1.9
9.6 - 5.3 ≥ 1.9
4.3 ≥ 1.9 ✅
We can check again with -6, since this and all numbers smaller than it should be a solution set.
-1.2(-6) - 5.3 ≥ 1.9
7.2 - 5.3 ≥ 1.9
1.9 ≥ 1.9 ✅
b ≤ -6 ✅You are a landscaper, and you are designing a fence to enclose part of a yard. The section to be enclosed is rectangular and has a width of 21 feet and a length of 38 feet. What length of fence, in feet, will you need to enclose this part of the yard? 59 60 118 120 798
Answer:
If you draw this out, you can see that total fence equation will be:
2L + 4W = 1200
Simplify, divide by 2
L + 2W = 600
L = (600-2W)
:
Area;
A = L*W
Substitute (600-2W) for L:
A = (600-2W)*W
A = -2W^2 + 600W; a quadratic equation
:
The dimension that will produce the greatest area will be the "axis of symmetry
which is: x = %28-b%29%2F%282a%29
:
In this equation a=-2, b=600
W = %28-600%29%2F%282%2A-2%29
W = %28-600%29%2F%28-4%29
W = +150 ft is the width
:
Find the length
L = 600 - 2(150)
L = 300 ft is the length
:
We can say the a field 300 by 150 gives he greatest area
:
This illustrated on a graph where y axis is the area and x axis is the width:

Solve the system of equation. Write the solution as a coordinate point
Answer:
(2,16)
Step-by-step explanation:
y=-x+18
y=8x
8x=-x+18
8x+x=9x
-x+x=0
9x=18
9x/9=x
18/9=2
x=2
y=8(2)
y=16
Answer:
(2,16)
Step-by-step explanation:
Step 1: Substitute -x+18 for y in y=8x:
-x+18=8x Add X to both sides
9x=18 Divide 9 by both sides
x=2
y=8(2)Plug in the new value for x(which is 2) into one of the equations
y=16
(2,16)

Albert bought 9 pounds of fish at a grocery store at $5 per pound for salmon and $3 per pound for catfish. He spent a total of $37 on the salmon and catfish. This can be represented using the following system of equations:5s +3c = 37 s + c = 9 How many pounds of salmon did Albert purchase?
Answer:
5 pounds
Step-by-step explanation:
To find that we simply solve the system of equationsSo make c the subject of the formula of equation 2[tex]s+c=9\\c=9-s[/tex] Substitute in equation 1 [tex]5s+3c=37\\5s+3(9-s)=37\\5s+27-3s=37\\5s-3s+27-(27)=37-(27)\\2s=10\\s=5[/tex] so that's 5 pounds of salmon5.
