Linear inequalities with two variables have infinitely many ordered pair solutions, which can be graphed by shading in the appropriate half of a rectangular coordinate plane. To graph the solution set of an inequality with two variables, first graph the boundary with a dashed or solid line depending on the inequality.

Joe has 16 pounds of fertilizer for his three gardens. He uses ⅜ of the fertilizer in his first garden and ¼ of the fertilizer in his second garden. What fraction of the fertilizer is left for the third garden? *
Answer:
3/8
Step-by-step explanation:
3/8 of 16 is 6
1/4 of 16 is 4
6+4 = 10
16-10 = 6
3/8 of 16 = 6
20% of the middle school students decided not to go skiing. How many middle school students are there if 40 stayed in the lodge?
Write a proportion for the situation.
Solve the problem. Show your work.
Answer:
Step-by-step explanation:
s(20/100)=40
20s=4000
s=200
So there are a total of 200 students.
Answer:
There are 200 middle school students
Step-by-step explanation:
The equation for this question can be: 40 is 20% of what. This can be simplified to 40 = 0.2x and then to get x by itself you divide 40 by 0.2 which is 200.
is 20 9/10 equal to 18
Answer:
1820 is equivalent to 910 because 18 x 10 = 20 x 9 = 180.

Find the missing angle according to the Triangle Sum Theorem.
Answer:
k = 140 degrees.
The missing INTERIOR angle is 40 degrees.
Step-by-step explanation:
The missing interior angle would be 40.
Triangle angle sum theorem states the 3 interior angles of a triangle sum to 180.
64+76+40 = 180
The exterior angle theorem states the exterior angle of a triangle is equal to the sum of the two remote interior angles of the triangle.
Exterior angle k = 64+76
k= 140

The range of F(x) = 6x3^x is all positive real numbers,
Someone solve this please?
Answer:
y = 4
Step-by-step explanation:
The perimeter of a polygon is the distance around the polygon. This can be found by adding up all of the side lengths. In this problem, one is given an expression for the perimeter and an expression for each side length. Using the formula for the perimeter, one can substitute in all of the given expressions and solve for the vairable.
(4y + 5) + (3y + 2) + (4y + 5) + (3y + 2) = 58 + 3y
Simplify,
4y + 5 + 3y + 2 + 4y + 5 + 3y + 2 = 58 + 3y
14y + 14 = 58 + 3y
Inverse operations,
14y + 14 = 58 + 3y
-3y -3y
11y + 14 = 58
-14 -14
11y = 44

Step-by-step explanation:
1. Break the Composite Figure into smaller shapes such as, rectangles, triangles, and squares.
2. Use the area formula for rectangles, triangles, and squares to find the area of each smaller shape.
3. Add the area of the smaller shapes together to get the area of the entire Composite Figure.
Hope this is correct and helps :[]).
Can you guys help plsssss I’m tireddddd
Answer:
#8 - 52°, #9 - 29°
Step-by-step explanation:
8. The two angles added together are a straight line, so they sum up to 180 degrees.
x + (2x + 24°) = 3x + 24° = 180°
3x + 24° = 180°
3x = 156°
x = 52°
9. Similar to #8. "Supplementary" means they add up to 180° (whether they are actually next to each other or not).
So, 4x + (2x + 6°) = 180°
6x + 6° = 180°
6x = 174°
x = 29°
Hope this helps. Get some rest. Zzzzz :)
All of the items in a bicycle shop are on sale for 30% off the regular price. Rene spends $74.90 to buy a bicycle and a
helmet (without taxes). If the regular price of the bicycle is $85, which equation can be used to find the regular price of the
helmet, h?
0.3(74.90+ h) - 85
0.3(85+) - 74.90
0.7(74.90+h) - 85
0.7(85+1) - 74.90
Answer:
0.7(85+)-74.90

Compare the areas. What is the ratio of the areas? SHOW YOUR WORK
Answer:
Ratio of the area of MIKE to TEAM = 9 : 1
Step-by-step explanation:
Ratio of similar shapes = square of the ratio of their corresponding sides
Since TEAM ~ MIKE, therefore the ratio of their areas = square of the height of MIKE : square of the height of TEAM
Ratio = 33² : 11²
Ratio = 1089 : 121
Ratio = 9 : 1
