Answer:
7.8
Step-by-step explanation:
25x=per hour of labor
16= parts
211 total price
25x+16=211
25x-16=211
25x=211
-16
25x=195
[tex]\frac{25x}{25} =\frac{195}{25}[/tex]
x=7.8
What is the solution to the system of equations
y= 2x – 1
y = -x +5
A. (-2, -3)
B. (-3,2)
C. (3, 2)
D. (2,3)
Answer:
D (2,3)
Step-by-step explanation:
1. Equate eq.1 n eq.2
hence 2x-1 = -x + 5
2x + x = 5 + 1 ( sign changes from -ve to +ve or +ve to -ve when we change sides ie. shifting something from LHS to RHS or vice-versa)
3x = 6
x = 6/3
x = 2
substitute the value of x in eq.1 or eq.2 to get y
substituting in eq.1
y = 2x -1
y = 2(2) - 1
y = 4 - 1
y = 3
hence coordinates are (x,y) = (2,3)

Tall hedges are shading a rose garden. At the time the gardener wants the garden to be in sunlight, a four- foot vertical pole casts a five foot shadow. Suppose that we want to cut the hedges back only to a height of 8 feet. How far must the edge of the garden be from the base of the hedge if we do not want any part of the rose garden to be in the shade?
Answer:
Step-by-step explanation:
A 4-ft pole casts a 5-ft shadow, so an 8-ft hedge casts a 10-ft shadow. Tge hedges must be 10 ft from the garden.
A standard six-sided die is rolled.
What is the probability of rolling a number greater than or equal to 3? Express your answer as a simplified fraction or a decimal rounded to four decimal places.
Tables
Keypad
Answer:
Step-by-step explanation:
There are six sides on the die...
1, 2, 3, 4, 5, 6
Greater than or equal to 3 includes 3, 4, 5, 6
This means 4 out of 6, or 4/6
4/6 simplified is 2/3

How many fewer students
Answer: 8 fewer students
Step-by-step explanation:
Drums - 32
Trombone - 16
Flute - 40
32 + 16 = 48
48 - 40 = 8
Hope it helps!
(Below is answer)
Step-by-step explanation: Since "fewer" means to subtract, we'll need to subtract 40 by 32.
1. 40 - 32 = ?
2. Zero cannot be subtracted by 2. Hence, we'll need to regroup.
Take one ten from the tens place. (Zero becomes 10)2a. 10 - 2 = 8
3. Solve again.
30 - 22 = 8Hence, our answer is 8.

The rate is 8 oz per cup.
Because 16x8=128, the number of cups is 128
Is Karla correct? Explain your answer.
Answer:
Karla is wrong, correct answer is 2 cupsStep-by-step explanation:
8 oz = 1 cup
the ratio 1 oz = 1/8 cupFind the answer using the ratio

Answer•Pic on the left
x = 8.36
y = 140.18°
• Pic on the right
x = 110°
Way to do• This one for the pic on the left
#Since the total degree of a triangle is 180° and one of the side known 90° (L) so the rest must be 90° (180° - 90° = 90°)
#known that the other side of triangle degree is (5x - 2)° and 6x° so... u can find the x! :D
90 = (5x - 2) + 6x
90 = 11x - 2
90 + 2 = 11x
92 = 11x
x = 92 : 11
x = 8.36 (2 decimal places)
#Now you know the x, you can now find the degree
#degree of (5x - 2)
5x - 2 =
5(8.36) - 2 =
41.81 - 2 = 39.81
#Since the y° is in the other side of the line of degre 39.81°, you can find it by minus it with 180° (straight line with no degree is 180°)
180° - 39.81° = 140.18
•This one for the pic on the right
#Lol this one is easy. I already told you before that the straight line degree is 180° and you can find one of the side if you know one of the degree side, so you can find it.
# Also as i said before, total triangle degree is 360°
#Find the degree of the other side of x° (only can find the degree of other side x because its inside the triangle)
Degree = 180° - 80° - 30° = 70°
#Now you can get x
x = 180° - 70° = 110°

Given that IG FT which of the following statements is true
Answer:
C
Step-by-step explanation:
Is x = 6 a solution to the equation 5(x – 3) = x + 13?
Follow the steps to find out.
1. Rewrite the equation 5(x – 3) = x + 13 with 6 substituted for x. Write a question mark over the equal sign to show that you're testing to see if the equation is true.
Write your answer in the space below.
Giving brainliest and thanks
Answer:
5(6 - 3) = 6 + 13; x = 6 is not a solution
Step-by-step explanation:
How many times does X squared minus 4X -12 cross the X axis
We can solve this problem using discriminant.
x^2-4x-12's discriminant is
(-4)^2-4*-12=16+48 which is clearly larger than 0
This means that it crosses over the axes 2 times.
In case you don't know what discriminant is, its in equation ax^2+bx+c
the discriminant is b^2-4ac.
If its positive it has 2 crosses with x axis, if negative then 0 crosses, if 0 then 1 cross.
