Multiply everything in the parentheses by .2
.2y + .4
Answer:
you find the x and y intersepts and draw the line
Step-by-step explanation:
if we break down the equasion in the end it's y=x+4 and from there we can find the intersepts by canceling out, y=x+4 becomes y=4 and 0=x+4 wich is x=-4
Assume that the larger number is m and the smaller one is n.
the larger is 10 less than twice the smaller, this means that:
m = 2n-10
the sum of the two is 38, this means that:
m+n = 38
substitute by the first equation in the second one:
2n-10+n=38
3n=48
n= 16
substitute by n in the first equation:
m=2n-10=2(16)-10= 22
based on this,
the larger number is 22 while the smaller number is 16
There are 4 boys and 7 girls with a total of 11. Now, how many 4 persons group combinations are possible.
=> 1 boy and 3 girls
=> 2 boys and 2 girls
=> 3 boys and 1 girl
Thus, there are 3 possible combinations that might happen.
Answer:
- The angle ∠2 = 4x = 4(36°) = 144°
Step-by-step explanation:
We know that when two lines meet or intersect, we get a linear pair of angles.
Linear pairs are basically two adjacent angles that form a line.
The measure of two adjacent angles forming a straight line is 180, meaning they are supplementary.
We are given that <1 and <2 forms a linear pair, and
m∠1 = 4m∠2
It means the angle ∠1 is 4 times the measure of angle ∠2.
Let the angle ∠1 be = x
As the angle 1 is 4 times the measure of angle ∠2, so
The angle 2 will be = 4x
As <1 and <2 forms a linear pair, thus the measure of the sum of <1 and <2 will be 180°, so
x + 4x = 180
5x = 180
divide both sides by 5
5x/5 = 180/5
x = 36°
Therefore,
- The angle ∠2 = 4x = 4(36°) = 144°
