Step-by-step explanation:
4x+8=7.2+5x
solve for x
Answer:
x = 0.8
Step-by-step explanation:
We are given this equation:
4x+8=7.2+5x
And we want to solve it for x.
To solve equations, we need to isolate the variable (x) on one side, and the numbers on the other side.
First, we can clear the numbers from the right side by subtracting 7.2 from both sides.
4x + 8 = 7.2 + 5x
-7.2 -7.2
_______________
4x + 0.8 = 5x
Now, we can subtract 4x from both sides.
4x + 0.8 = 5x
-4x -4x
_______________
0.8 = x
This can be rewritten to be: x = 0.8
The value of x is 0.8

Write an equation of the line with a slope of -2/7 and a y-intercept of 5
Y=_____
Answer:
y= -2/7 +5
Step-by-step explanation:
The equation of the line with a slope of -2/7 and a y-intercept of 5 is y=-2/7 x+5.
Given that, slope (m) =-2/7 and y-intercept (c) =5.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The standard form of the slope intercept form is y=mx+c.
Put m=-2/7 and c=5 in y=mx+c, we get
y=-2/7 x+5
Therefore, the equation of the line with a slope of -2/7 and a y-intercept of 5 is y=-2/7 x+5.

if the value of c is negative, you would need zero pairs to model the factorization of the polynomial. the x-tiles on the board determine what the constants are in the factors. the product of these constants is equal to the value of c, so you would need positive tiles on one side of the x-squared tile and negative x-tiles on the other side to have opposite signs on the constants. opposite signs on the constants will result in a negative value for c when multiplying the factors.
Answer:
value of c is negative
constant are in factor bla bla.

A save percentage in lacrosse is found by dividing the number of saves by the number of shots faced. A
lacrosse goalie saved 7 of 11 shots. How many additional consecutive saves s must the goalie make to
raise his save percentage to 0.850?
Answer:
The goalie needs to make 16 more saves in a row.
Step-by-step explanation:
Let n be the number of additional saves needed.
[tex]\frac{7+n}{11+n}\geq 0.85[/tex]
[tex]7+n\geq 0.85(11+n)\\[/tex]
[tex]7+n\geq 9.35+0.85n[/tex]

-7x-2y= -13
x-2y= 11
Solve the question with substitution and show work
Answer:
x=3,y= -4
Step-by-step explanation:
ii) x-2y=11
x=11+2y-----(i)
Now,
i) -7x-2y= -13
or, -7(11+2y)-2y= -13
or, -77-14y-2y = -13
or -14y-2y = -13+77
or -16y = 64
or y =64÷(-16)
:: y = -4
Again,
(ii) x-2y= 11
or x-2(-4)= 11
or x+8 = 11
or x = 11-8
:: x = 3

Calculate the height of a right circular cylinder with a surface area of 300 square inches and a radius of 5 inches. a. 2.45 inches c. 8.25 inches b. 4.55 inches d. 3.65 inches
Answer:
The height of the right circular cylinder is 4.55 inches ⇒ b
Step-by-step explanation:
The formula of the surface area of a right circular cylinder is
S.A = 2πrh + 2πr², where
r is its radiush is its height∵ The surface area of a right circular cylinder is 300 square inches
∴ S.A = 300 in.²
∵ Its radius is 5 inches
∴ r = 5 in.
∵ π = 3.14
→ Substitute them in the rule above
∵ 300 = 2(3.14)(5)(h) + 2(3.14)(5)²
∴ 300 = 31.4h + 157
→ Subtract 157 from both sides
∵ 300 - 157 = 31.4h + 157 - 157
∴ 143 = 31.4h
→ Divide both sides by 31.4
∵ 4.554140127 = h
∴ 4.55 = h
∴ The height of the right circular cylinder is 4.55 inches

The value of x=10 and m∠SOP=50° and m∠ROQ=50° .
When two straight lines intersect each other at a point then vertical angles are formed , there are two pair of vertically opposite angles and also , the vertically opposite angles are equal.
In the given question
m∠SOP = (5x)° ...(i)
and
m∠ROQ = (4x+10)° ...(ii)
and Since the angles m∠SOP and m∠ROQ are vertically opposite , they will be equal .
On equating we get ,
m∠SOP=m∠ROQ
Substituting the values from equation (i) and (ii) we get ,
5x=4x+10
5x-4x=10
x=10.
Substituting the value of x in equation (i) we get ,
m∠SOP = (5*10)° = 50°
Substituting the value of x in equation (ii) we get ,
m∠ROQ = (4*10+10)° = (40+10)° = 50°
Therefore , the value of x=10 and m∠SOP=50° and m∠ROQ=50° .
