Answer:
x=15
Step-by-step explanation:
Well, you have 2 numbers that sum up to 90 (the angle) so you can first minus the one you know, making your number from 90-30=60. Now all thats left is the 4x=60, which you can do 60/4=15 to get your answer that x=15.
Answer:
x = 15
Step-by-step explanation:
The sum of 30 and 4x = 90, that is
4x + 30 = 90 ← equation to solve
Subtract 30 from both sides
4x = 60 ( divide both sides by 4 )
x = 15

What is the value of 3ab + c when a = 0.32, b = 0.45, and c = 7.2?
Answers
Answer:
7.632
Step-by-step explanation:
When solving this equation, you need to substitute the number equal to a where the a is in the equation, along with the b and c. So since a=0.32, then I would put that where the a is in 3ab+c. Same goes with the other letters.
a = 0.32
b = 0.45
c = 7.2
3ab+c
3(0.32)(0.45)+7.2 *Multiply the 3 to 0.32
0.96(0.45)+7.2 *Multiply the 0.96 to 0.45
0.432+7.2 *Add

Solve the equation for p, then justify your reasoning. -9p - 17 = 10
Answers
Answer:
p=-17/9 or p=-1.8889
Step-by-step explanation:
-9p-17=10
add 17 to each side
-9p-17+17=10+17
-9p=17
divide both sides by -9
-9p/-9=17/-9
p=-17/9
or p=-1.8889
Solution of equation - 9p - 17 = 10 is p = -3.
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x – 5 = 16 is an equation.
Given equation
- 9p - 17 = 10
Add 17 to both sides
- 9p - 17 + 17 = 10 + 17
Adding the numbers
- 9p = 10 + 17
Adding the numbers
- 9p = 27
Divide both sides by - 9
-9p/ - 9 = 27/ - 9
Cancel terms that are in both the numerator and denominator
p = 27/ - 9
Divide the numbers
p = -3
Hence, p = -3 is the solution for equation - 9p - 17 = 10

Explanation:
Part A.
1. You have provided an estimate of 600 minutes per month.
__
2. The cheapest plan is likely to be Plan 6 (Public Mobile), as it has no per-minute charge.
__
Part B.
1. Table 2.
See the first attachment for Table 2. For the chosen plan, there is no per-minute charge, so the monthly charge is the same for all numbers of minutes.
__
2. Rate of Change and Slope (m)
a) Adding a minute adds $0 to the cost
b) The rate of change (m) is 0/1 = 0 (dollars per minute)
__
3. Initial value (b)
a) The plan costs $24.00 when no minutes are used.
b) The initial value (b) is 24.
__
4. Equation of the line
a) Filling the found values of m and b into the equation of the line, we have ...
y = mx + b
y = 0x + 24
y = 24 . . . . . . simplified
__
Part C.
Table 3 can be found in the second attachment.
The b in each case is the value from the Monthly Cost column of Table 1.
The m in each case is the value from the Cost per minute column of Table 1.
The equation is found by copying the values of m and b into y = mx + b.
The number in the last column is found by multiplying the minutes (x) by m, then adding b. For example, your cost for Plan 5 (BELL) is ...
y = 0.10x + 10
y = (0.10)(600) +10 = 60 +10 = 70

Based on similar triangle;
14/49 = x+5/9x+1
Cross multiply
49(x+5) = 14(9x+1)
49x + 245 = 126x + 14
49x - 126x = 14 - 245
-77x = -231
x = -231/-77
x = 3
Hence the value of x is 3

a rectangle has a length 3 meters more than three times the width. the area of the rectangle is less than 90 meters squared. write an expression that represents all possible widths (use the variable x) of the rectangle. write your answer as an inequality, a < x < b.
Answers
Answer: -6<x<5
Step-by-step explanation:
Given
Length is 3 m more than three times the width
Suppose width is x
So, the length is 3x+3
The area of a rectangle is [tex]length\times width[/tex]
Area= [tex](3x+3)x<90[/tex]
[tex]\Rightarrow 3x^2+3x-90<0\\\Rightarrow x^2+x-30<0\\\Rightarrow x^2+6x-5x-30<0\\\Rightarrow (x+6)(x-5)<0\\\Rightarrow -6<x<5[/tex]
