A construction crew is lengthening a road. The crew is adding 6 miles to the road each week. The road originally measured 52 miles long. The crew's goal is given by 6x+52>130, where x is the number of weeks the crew works.
6x + 52 > 130
Subtract 52 from both sides:
6x > 78
Divide both sides by 6:
X > 78/6
X > 13

D is the 4th letter of the alphabet and u have 5 d which means 4×5=20(repeat the same step for the other letters
J is 10thh so 7×10=70
Next letter is F, you have 2 f's
F is the 6th letter of the alphabet

Into the pair of fractions as a pair of fractions with the smallest common denominator between the two fractions two over three and 5/6
Answer:
A pair of fractions as a pair of fractions with the smallest common denominator are [tex]\frac{4}{6}[/tex] and [tex]\frac{5}{6}[/tex] .
Step-by-step explanation:
Given fractions are [tex]\frac{2}{3}[/tex] and [tex]\frac{5}{6}[/tex]
Find L.C.M (least common multiple) of [tex]3[/tex] and [tex]6[/tex]
3 = 3 × 1
6 = 2 × 3 × 1
L.C.M (least common multiple) of [tex]3[/tex] and [tex]6[/tex] is [tex]3[/tex]
Multiply numerator and denominator of [tex]\frac{2}{3}[/tex] by [tex]2[/tex].
[tex]\frac{2}{3}=\frac{2(2)}{3(2)} =\frac{4}{6}[/tex]
Therefore, pair of fractions as a pair of fractions with the smallest common denominator are [tex]\frac{4}{6}[/tex] and [tex]\frac{5}{6}[/tex]
1. A carpenter makes bookcases in 2 sizes, large and small. It takes 4 hours 2 points
to make a large bookcase and 2 hours to make a small one. The carpenter
can spend only 32 hours per week making bookcases and must make at
least 2 of the large and at least 4 of the small each week. Create a system
of linear inequalities to model this situation. *
The system of linear inequalities to model this situation is 4x+2y≤32, x≥2, y≥4. The correct option is (a).
The inequality 4x + 2y ≤ 32 represents the total number of hours available per week, which is limited to 32 hours.
The inequality x ≥ 2 represents that the carpenter must make at least 2 large bookcases per week.
The inequality y ≥ 4 represents that the carpenter must make at least 4 small bookcases per week.
These inequalities ensure that the carpenter stays within the time constraint of 32 hours and fulfills the minimum quantity requirements for both large and small bookcases.
Thus, the correct option is (a).

A total of 762 people, consisting of parents, students, and teachers, attended the Community Fair. If 212 parents and 386 students were at the event, how many teachers attended?
Answer:
[tex]\boxed{\textsf{ The number of Teachers that attented is \textbf{ 164 } .}}[/tex]
Step-by-step explanation:
Here it's given that a total of 762 people consisting of parents, students, and teachers, attended the Community Fair. There were 212 parents and 386 students at the fair .That is ,
Number of students:-
[tex]\sf\implies n(students) = 386 [/tex]
Number of parents :-
[tex]\sf\implies n(parents) = 212 [/tex]
Number of teachers :-
[tex]\sf\implies n(teachers) = ? [/tex]
Here the Number of teachers could be simply find out by subtracting the number of students and teachers from the total number of attendees .
[tex]\sf\implies n_{(teachers)}= n_{(total)}- n_{(students)}- n_{(parents)} \\\\\sf\implies n_{(teachers)}= 762 - 386 - 212 \\\\\sf\implies n_{(teachers)}= 762 - 598 \\\\\sf\implies\boxed{\pink{\frak{ n_{(teachers)}= 164 }}}[/tex]
Write the quadratic equation and solve by using the general formula. "Find two consecutive numbers in which the double of the square of the smaller number plus the square of the greater number is 121"
Answer: 6 and 7
Step-by-step explanation:
Let the numbers be x and x + 1
We can form and equation as:
2(x²) + (x+1)² = 121
2x² + (x + 1)(x + 1) = 121
2x² + x² + x + x + 1 = 121
3x² + 2x = 121 - 1
3x² + 2x = 120
3x² + 2x - 120 = 0
3x² - 18x + 20x - 120 = 0
3x(x - 6) + 20(x - 6)
Therefore, x - 6 = 0
x = 0 + 6
x = 6
The numbers are 6 and 7
The two numbers given in the statement is required.
The two numbers can be [tex]6,7[/tex] or [tex]-\dfrac{20}{3},-\dfrac{17}{3}[/tex]
Quadratic equationLet [tex]x[/tex] be the first number
[tex]x+1[/tex] be the next consecutive number
From the statement we get
[tex]2x^2+(x+1)^2=121\\\Rightarrow 2x^2+x^2+2x+1=121\\\Rightarrow 3x^2+2x-120=0\\\Rightarrow x=\dfrac{-2\pm \sqrt{2^2-4\times3\left(-120\right)}}{2\times3}\\\Rightarrow x=6,-\dfrac{20}{3}[/tex]
If [tex]x=6[/tex]
the other number is [tex]x+1=6+1=7[/tex]
If [tex]x=-\dfrac{20}{3}[/tex]
the other number is [tex]x+1=-\dfrac{20}{3}+1=-\dfrac{17}{3}[/tex]

1) Pat mixes 5 quarts yellow, 2 quarts
orange and 1 quart whte paint .If she
wants to make 24 quarts
of this mixture , how many quarts of
each color does she need?
Answer:
5 quarts yellow + 2 quarts orange + 1 quart white = 8 total quarts.
To make 24 quarts you need 3 times as much, because 8 * 3 = 24.
Multiply each measurement by 3:
5 quarts yellow --> 15 quarts yellow
2 quarts orange --> 6 quarts orange
1 quart white --> 3 quarts white
What is the area of and the perimeter of this triangle?
A= 33 square yards; P= 40 yards
A= 40 square yards; P= 33 yards
A= 80 square yards; P= 33 yards
A= 25 square yards; P= 28 yards
Answer:
A = 40 square yards; P = 33 yards.
Step-by-step explanation:
Perimeter of the triangle
= ( 8 + 15 + 10)
= 36 yards.
Area of the right angled triangle
= 1 /2 * 10 * 8
= 40 square yards.

-2x -4y = -10
-7x -4y = -15
What is this in a ordered pair? (x,y)
Answer:
x=1,y=2
-2x-4y= -10 maltiple by -1 then 2x +4y
-7x-4y= -15
therfore 2x+4y=10
-7x-4y=-15 to find x or y you must zero one of them
ther fore 4y-4y=0
then 2x+(-7x)= -5x
-5x=10 +(-15) =-5
-5x = -5
divide by -5 both side,
x =1
to get the value of y the value of x supersed in to equation
-2(1) -4y = -10
-4y =-10 +2
-4y = -8 both dived by -4
y=2

Tenley wants to exercise at least 15 hours per week. She walks at a speed of three miles per hour and bikes at a speed of 10 miles per hour. She wants to cover at least 90 miles total in her weekly workouts, biking no more than 10 hours and walking no more than 12 hours.
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of hours spent on walking and let y represent the number of hours spent on biking.
Tenley wants to exercise at least 15 hours per week, therefore:
x + y ≥ 15 (1)
Tenley cover at least 90 miles total in her weekly workout, therefore:
3x + 10y ≥ 90 (2)
x ≤ 12, y ≤ 10 (3)

Katrina has $210 in her savings account. She plans to buy books for her friends for Christmas. The books cost $7 per book. Which equation best represents this situation? Let y represent the amount of money in Katrina's account and x represents the number of books she purchases.
what is the correct answer
y=210-7x
y=7x+210
y=210x+7
y=-7+210x
Answer:
Option 1 y = 210 - 7x
Step-by-step explanation:
Since she will be buying "x" amount of books she will lose money because she has to pay for them. Each book costs $7 so if she buys "x" books she will lose 7x dollars. Therefore the right equation would be...
y = 210 - 7x (which is the first option)
