I think u would just do the work and add the decimal in
Answer:
24
Step-by-step explanation:
50+32=82
300-82=218
218÷15=24
Answer:
a should be 45
b should be 90
c should also be 45
Step-by-step explanation:
I know this because 180-135=45 for a
since c is also 45, beside c should be 135.
which means those angles are congruent.
since a triangle equals 180 degrees all together 180-45-45=90
so b is 90
correct me if im wrong
Answer:
72
Step-by-step explanation:
<1 and <2 are not equal to each other
Let the angle directly above angle 2 (on the right side of the line) be angle 3
<1 and <3 are corresponding angle, which means they are equal
<2 and <3 are supplementary angles since the form a line
<2 + <3 = 180
We know <1 = <3
<1 + <3 = 180
We are given <1 = 2x+12 and <2 = 3x+18
2x+12 + 3x+18 = 180
Combine like terms
5x+30 = 180
Subtract 30 from each side
5x+30-30 = 180-30
5x= 150
Divide each side by 5
5x/5 = 150/5
x=30
<1 = 2x+12
Substitute 30 in for x to find angle 1
= 2*30 +12
=60+12
= 72
Expanded forms of numbers show the value of each digit . Expanded forms of a number are written into an addition sentence. This can be done in scientific notation, fraction form, or addition statement of numbers based on each number's place value.
Example: 1.059
1 + .05 + .009 =1.059
thus;
1
+ . 05
<u>+ . 009</u>
1. 059
or,
1x1 + 0 x .1 + 5 x .01 + 9 x .001=1.059
where;
1 x 1 =1
0 x .1 =0
5 x .01= .05
9 x .001= .009
Add all the results. The sum is 1.059
