Answer:
x = 5
Step-by-step explanation:
Your goal is to isolate x
3x + 7 = 22
Subtract 7 from both sides and you are left with
3x = 15
In order to isolate x divide both sides by 3
x = 5
Answer:
Container holds more than 3 cups of sugar.
Step-by-step explanation:
We are given that,
Amount of sugar used by Dee = cups.
Now, as the container holds 3 times the amount of sugar used by Dee.
So, the amount of sugar container holds = = = 7 cups.
Thus, the container can hold 7 cups of sugar, which are greater than 3 cups of sugar.
Hence, the container holds more than 3 cups of sugar.
When the container is filled with water it can hold approximately b. 18g.
Step-by-step explanation:
Step 1:
The edge length of the container is 16 inches long.
The volume of a cube is obtained by taking the cube of the edge length.
The volume of the container cubic inches.
So the volume of the cube-shaped container is 4,096 cubic inches.
Step 2:
If 1 gallon equals 231 cubic inches, we need to determine how much gallons could be held in 4,096 cubic inches.
To do this we divide the volume of the container by the cubic inches in one gallon.
The number of gallons in the container gallons.
Rounding this off, we get that the container can hold 18 gallons of water.
Answer:
z = 7 and z = 69
Step-by-step explanation:
In the given figure, two lines are cut each other.
Here we have to use the following property.
If the two lines intersect each other, then the opposite sides are equal.
Therefore, 11x + 34 = 111
Now we have to find the value of x.
Solve for x.
11x = 111 - 34
11x = 77
Dividing both sides by 11, we get
x = 77/11
<u> x = 7</u>
Now we have to find the value of z.
Adjacent angles add upto 180 in a straight line.
Therefore, 111 + z = 180
Subtract 111 on both sides, we get
111 + z -111 = 180 - 111
<u>z = 69</u>
Therefore, z = 7 and z = 69
Hope you will understand the concept.
Thank you.
