Answer:
-10.4
Step-by-step explanation:
Assume that the number we are looking for is x.
Now, we want to get 10 times the sum of half the number and 6 and equate this expression to 8. Then we can solve for x
step by step
half the number is 0.5x
the sum of half the number and 6 is 0.5x + 6
10 times the sum of half the number and 6 is 10(0.5x +6)
10 times the sum of half the number and 6 equals 8 is 10(0.5x+6) = 8
Now solve for x
10(0.5x + 6) = 8
5x + 60 = 8
5x = 8 - 60
5x = -52
x = -52/5
x = -10.4

For the equation 4(2x-3)-(mx+5)=5x+b to be an identity, which of the following must be true about the constants m and b? Show your work
(1) m = 3 and b = -7
(2) m = 8 and b = 17
(3) m = -3 and b = -15
(4) m = 3 and b = 17
Given:
The equation is
[tex]4(2x-3)-(mx+5)=5x+b[/tex]
To find:
The values of m and b.
Solution:
We have,
[tex]4(2x-3)-(mx+5)=5x+b[/tex]
Using distributive property, we get
[tex]8x-12-mx-5=5x+b[/tex]
On combining like terms, we get
[tex](8-m)x+(-12-5)=5x+b[/tex]
[tex](8-m)x-17=5x+b[/tex]
On comparing both sides, we get
[tex](8-m)=5[/tex]
[tex]-m=5-8[/tex]
[tex]-m=-3[/tex]
[tex]m=3[/tex]
And,
[tex]b=-17[/tex]
Therefore, m = 3 and b = 17.
Note: All options are incorrect.
what is 0.0042 as a fraction in simplest form
Answer:
21/5000
Step-by-step explanation:
0.0042 takes the form of 21/5000 as a fraction.
Answer:
21/500
Step-by-step explanation:
0.0042 = 42/1000, (There is 4 digits to the right of the decimal point)
42 is an even number so, divide by 2 to simplify.
42/2 = 21 and 1000/2 = 500
21/500 is your final answer because 21 is divisible by 7 and 3 but 500 cannot be divided by either of those to get a whole number.

15. What is the value of x in the figure bellow?
Answer:
x=22.5
Step-by-step explanation:
suppose you are organizing a party and have a budget of b dollars for the appetizers. You plan to order v vegetarian spring rolls at $0.75 each and s shrimp rolls at $0.95 each.
The equation 0.75v+0.95s=b represents this constraint.
Solve 0.75v+0.95s=b for v
When would it be most helpful to use this equation?
Answer:
v = b/0.75 - 0.95s/0.75
Or
v = (b - 0.95s) / 0.75
Step-by-step explanation:
Solve 0.75v + 0.95s = b for v
This means making v the subject of the formula
0.75v + 0.95s = b
Subtract 0.95s from both sides
0.75v + 0.95s - 0.95s = b - 0.95s
0.75v = b - 0.95s
Divide both sides by 0.75
v = (b - 0.95s) / 0.75
v = b/0.75 - 0.95s/0.75
The equation will be useful in determining the number of vegetarian

Which ordered pair is the solution to the system of linear equations Negative 5 x + y = 26 and 2 x minus 7 y = 16?
9514 1404 393
Answer:
(-6, -4)
Step-by-step explanation:
If you're going to use technology to answer your questions, you may as well use appropriate technology: a graphing calculator. It shows the solution to the system is the ordered pair (-6, -4).
__
The first of the given equations can be solved for y, then that used to substitute for y in the second equation.
y = 5x +26
2x -7(5x +26) = 16
2x -35x -182 = 16
-198 = 33x . . . . . . . . add 33x-16
-6 = x . . . . . . . . . . . . divide by 33
y = 5(-6) +26 = -4 . . . find y
The solution is (x, y) = (-6, -4).

Find the product of -2*(-4)*9. Describe how you use the properties of
multiplication to find the product. Is the product positive or negative?
Answer:
72
Step-by-step explanation:
-2 x -4 = 8
8 x 9 = 72
Hope this helps! Please mark Brainliest!
Answer:
72 = Positive
Step-by-step explanation:
The property we use,
→ Associative property
Now the product will be,
→ (-2 × -4) × 9
→ 8 × 9 = 72
→ -2 × (-4 × 9)
→ -2 × (-36) = 72
Then the required sign is,
→ Positive (+ve)
Hence, the product is 72.

Line ST and point V are shown on the graph. Line WW is to be drawn on the graph such that it is perpendicular to line ST. If the coordinates of point Ware (-1, y), what is the value of y?
-5
2
3
-7
Answer:
3
Step-by-step explanation:
We can use the formula of slope to find this answer.
The formula to find the slope is y2-y1/x2-x1.
The slope of line ST is 1/5: 2-0/5-(-5); 2/10=1/5
We know that for two lines to be perpendicular, they have to have reciprocal opposite slopes. For example, if the slope of a line is 2/1 then the slope of a line perpendicular is -1/2.
Therefore, the perpendicular line should have a slope of: 1/5------>-5
To find which answer it is, follow the steps below:
y2-y1/x2-x1
plugin known values
-2-y1/0-(-1)
-2-y1/1
In order to make this -5, y1 needs to be 3
-2-3/1=-5
3 is the correct value
The value of y is 3.
What is slope?The slope of a line is a measure of its steepness.
Given:
Ware( -1, y)
Now,
slope of line ST =2-0/5-(-5)
slope=1/5
As two lines to be perpendicular, they have to have reciprocal opposite slopes.
Thus, the perpendicular line slope =-5
Now, y2-y1/x2-x1
= -2-y1/0-(-1)
= -2-y1/1
= -2-3/1
=-5
hence, the value of y is 3.

NEED HELP! A line has a slope of 9/7 and a y-intercept of 1/3. Which of the following is an equation of the line?
A 27x - 21y = -7
B 27x + 21y = 1
C 9x + 7y = 3
D 7x - 9y = -3
Please show work so I could understand this!
Answer:
A
Step-by-step explanation:
Take a look at the slope-intercept form of the equation .
[tex]y=mx+c[/tex]
Slope of 9/7 and y-intercept of 1/3 means replace m which is slope and c is the y-intercept which becomes
[tex]y=\frac{9}{7}x+\frac{1}{3}[/tex]
now we take LCM of 7 and 3 which becomes
[tex]y=\frac{27x+7}{21}[/tex]
and then,
[tex]21y=27x+7[/tex]
so A is our Answer
if arrange the equation accordingly
[tex]27x-21y=-7[/tex]
