Answer:
=5a+7b
Step-by-step explanation:
Expand: 5(a + 2b): 5a + 10b
=5a+10b-3b
<em>Add similar elements: 10b-3b=7b
</em>=5a +7b
If x=girls,
then we have 3x boys.
We know that all children are boys+girls, so x+3x, which is 4x and 4x is 48, so one x is 12.
So there are 12 girls and 36 boys.
Answer:
2 years
Step-by-step explanation:
3% of $550 = 0.03 * $550 = $16.50
3% interest on $550 for 1 year is $16.50
$33/$16.50 = 2
Since 2 * $16.50 = $33, the loan was for 2 years.
Measure of arc TS is equal to the central angle SPT. TPR is a semi circle so =180
TPR-RPS=SPT
180-110=70
Arc TS = 70 degrees
The measure of the angle 2 is 133° and the measure of the angle 3 is 47°.
<h3>Classification Angles</h3>
They are a lot of classifications for angles like: complementary angles, supplementary angles, right angles, and others. See below:
- complementary angles - two angles whose the sum is equal to 90°.
- supplementary angles - two angles whose the sum is equal to 180°.
- right angles - angles whose the measure is 90°.
From the figure, it is possible to see that:
- the angles 1 and 3 are supplementary angles
- the angles 2 and 3 are supplementary angles
Therefore, if angle1 is 133°, you have:
angle_1 + angle_3 = 180
133 + angle_3 = 180
angle_3=180-133
angle_3=47°
If angle3 is 47°, you have:
angle_3 + angle_2 = 180
47+ angle_2 = 180
angle_2=180-47
angle_2=133°
