Answer:
x = 5
Step-by-step explanation:
Given
3x - 5(x - 5) = - 7 + 2x + 12 ← distribute and simplify left side
3x - 5x + 25 = 2x + 5
- 2x + 25 = 2x + 5 ( subtract 2x from both sides )
- 4x + 25 = 5 ( subtract 25 from both sides )
- 4x = - 20 ( divide both sides by - 4 )
x = 5

(Sorry i am not good at math) Write an expression for the operation described below.
multiply 10 by t
Answer:
Multiplying 10 by t will not work under most circumstances so it would be 10t which means 10*t but if you substitute the t for lets say 4 then you would get 40 but that wasn’t the question so your answer is 10t

The expressions that are equivalent to [tex]3\frac{1}{4} -(-\frac{5}{8} )[/tex] are
[tex]3\frac{1}{4} +(\frac{5}{8} ) \\\\3\frac{1}{4} +(+\frac{5}{8} )[/tex]
for understanding check the calcualtions here
Calculationan expression is the combination of numbers and operators like +, - * or /
If we have any equal sign then it is an equation .
Given expression is :
[tex]3\frac{1}{4} -(-\frac{5}{8} )[/tex]
to find out equivalent expression we remove the parentheisis by multiplying negative inside the parenthesis
Negative times negative becomes positive
first fraction is positive . So it remains the same
Multiply negative inside the parenthesis . Negative times negative is positive
so, the equivalent expressions are
[tex]3\frac{1}{4} +(\frac{5}{8} ) \\\\3\frac{1}{4} +(+\frac{5}{8} )[/tex]

Answer:
An equation for the parabola would be y²=-19x.
Since we have x=4.75 for the directrix, this tells us that the parabola's axis of symmetry runs parallel to the x-axis. This means we will use the standard form
(y-k)²=4p(x-h), where (h, k) is the vertex, (h+p, k) is the focus and x=h-p is the directrix.
Beginning with the directrix:
x=h-p=4.75
h-p=4.75
Since the vertex is at (0, 0), this means h=0 and k=0:
0-p=4.75
-p=4.75
p=-4.75
Substituting this into the standard form as well as our values for h and k we have:
(y-0)²=4(-4.75)(x-0)
y²=-19x

(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.
(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.
What is velocity?Velocity is the rate of change of displacement with time. The velocity of the cars depends on displacement and time of motion.
First velocity of the car at the 0.25 meter markThe first velocity is calculated as follows;
v1 = 0.25 m / t1
let t₁ = 2 s
v₁ = 0.25/2
v₁ = 0.125 m/s
Second velocity of the car at the 0.5 meter markv2 = 0.25 m / (t2 – t1)
let t₂ = 3 s
v₂ = 0.25(3 - 2)
v₂ = 0.25 m/s
The complete question is below:
Calculate the first and second velocities of the car with two washers attached to the pulley, using the formulas
v1 = 0.25 m / t1, and
v2 = 0.25 m / (t2 – t1)

Bob's monthly net income is $3,000. Bob pays $950 for rent, $250 for all
utilities, and $1,850 in other fixed and variable expenses. What is Bob's
cash flow?
A.Negative cash flow, $50
B.Negative cash flow, $3,050
C.ositive cash flow, $3,050
D.Positive cash flow, $50
Answer:
A: Negative cash flow, $50
Step-by-step explanation:
Bob makes $3000 a month.
Every month he has to pay $950:
3000 - 950 = 2050
Pay an additional $250:
2050 - 250 = 1800
And another additional $1850:
1800 - 1850 = -50
Therefore, he has a negative cash flow of $50 a month.

From his house, Shane could drive due north to get to his parents' house or he could drive due east to get to his grandparents' house. It is 8 miles from Shane's house to his parents' house and a straight-line distance of 17 miles from his parents' house to his grandparents' house. How far is Shane from his grandparents' house?
Answer:
15 miles
Step-by-step explanation:
It is given that,
Shane could drive due north to get to his parents' house or he could drive due east to get to his grandparents' house.
It is 8 miles from Shane's house to his parents' house and a straight-line distance of 17 miles from his parents' house to his grandparents' house.
It can be calculated by considering a right angled triangle. Using pythagoras theorem, we can find the distance between Shane from his grandparents' house. Let it is d.
[tex]d^2=\sqrt{17^2-8^2} \\\\=15\ \text{miles}[/tex]
Hence, Shane is 15 miles from his grandparents' house.
