Answer:
19 boys
Step-by-step explanation:
38 kids on the bus
1/2 are girls, that means 1/2 are boys
1/2 * 38 = 19
There are 19 girls and 19 boys
Answer:
x = 0, y = 7
Step-by-step explanation:
Solving a system of equations using substitution requires one side to be equal to a variable present in the equation, in this case x or y. We should simplify the equation using elimination before substituting to reduce the chance of error.
In order to use the elimination method, you have to create variables that have the same coefficient—then you can eliminate them. These equations arew already aligned for us.
3x - 10y=-70
-<u> 4x +9y = 63</u>
-x + y = 7
Now, for substitution, the equation must be set to a variable.
-x + y = 7
y = x + 7
Next, plug the equation in where applicable in another equation.
4x +9(x + 7) = 63
4x + 9x + 63 = 63
13x = 0
x = 0
The final step of substitution is to plug the known variable into an equation to find the other variable.
3(0) - 10y=-70
0 - 10y = -70
10y = 70
y = 7
I guarantee you this answer is correct, I worked it out using other methods and graphing prior to submitting this answer.
24 cubes can filled up the prism
Solution:
The image of the question is attached below.
Given data:
Length of the prism = 2 cm
Breadth of the prism = 1 cm
Height of the prism = 
cm
Volume of the prism = length × breadth × height
cubic cm
Volume of the prism = 3 cubic cm
Side length of the cube = 
cm
Volume of the cube = side × side × side
cubic cm
Volume of the cube = 
cm
Number of cubes = 24
Hence 24 cubes can filled up the prism.
