Dave has $358 in his bank account. He wants to prepay his cell phone bill for the next three months. His monthly cell phone bill is $78. He also needs to pay his electric bill, which is $135. How much money will Dave need to add to his account to cover all his bills?
Answer:
$11
Step-by-step explanation:
Given data
Total amount= $358
Monthly cell phone bill= $78
Bill for the three months = 78*3= $234
Electtrcilty bill = $135
Total bills= $234+ $135=$369
Hence, the amount to be added= 369-358 =$11

Express the following equation in the form ax^2+bx+c=0:
(4a+3)^2=(a+5)(a−2)
Answer:
15a² + 21a + 19 = 0
Step-by-step explanation:
Given
(4a + 3)² = (a + 5)(a - 2)
(4a + 3)(4a + 3) = (a + 5)(a - 2 ) ← expand both sides using FOIL
16a² + 24a + 9 = a² + 3a - 10 ( subtract a² + 3a - 10 from both sides )
16a² - a² + 24a - 3a + 9 + 10 = 0 ← collect like terms
15a² + 21a + 19 = 0
GIVING BRAINLEST FOR SIMPLE 7TH GRADE MATH PROBLEM.
Answer:
B. 60deg
Step-by-step explanation:
Both the sum of the third angle in the triangle and x has to be 180deg, as they sum to a half angle;
and the sum of angles in any triangle is 180deg.
We know that x = 180deg - (180deg - 28deg - 32deg) = 180deg - 180deg + 28deg + 32deg = 60deg
Also, note that x is drawn as smaller than a right angle. Unless the picture was made specifically to confuse us, we know that the only answer could be B.
Answer:
The exterior angle measures 60°
Step-by-step explanation:
Using the angles we already have we can determine that the missing interior angle is 120 since the interior angles of a triangle add up to 180°. So the missing interior and and the missing exterior angle are supplementary meaning they add up to 180. so 180-120=60°

Find the area of a circle with a radius of 3 inches. Use 3.14 for pi.
Answer:
28.26
Step-by-step explanation:
3×3=9
9×3.14=28.26
Answer:
The answer is 28.26
Step-by-step explanation:
Why? Ok so here it is:
The formula is (pi)(r)squared
In this case, you will replace pi with 3.14 and replace r with 3 because that's the radius.
So it would be (3.14)(3)
You would get 9.42
Now you just need to square it
When squared, you'll get 28.26 inches squared

14p - 8 = 22 + 20p
could someone help
Answer:
P = -5
Step-by-step explanation:
First try to get the variable p by its self and the whole numbers on the opposite side.
14p - 8 = 22 + 20p
-14p - 14 p
-8 = 22 + 6p
-22 -22
-30 = 6p
Then divide to get P alone
-30 = 6p
/6 /6
-5 = p
