Answer:
x = -4
y = -25
Step-by-step explanation:
Since one of the equations is already set with one variable as the subject ( y = 7x + 3) substitute that into the one below it:
9x - 2y = 14
9x - 2(7x + 3) = 14
9x - 14x - 6 = 14
-5x = 20
x = -4
Substitute this into one of the equations and solve for the other variable:
y = 7x + 3
y = 7(-4) + 3)
y = -28 + 3
y = -25
hope this helps!
Answer:
(- 4, - 25 )
Step-by-step explanation:
Given the 2 equations
y = 7x + 3 → (1)
9x - 2y = 14 → (2)
Substitute y = 7x + 3 into (2)
9x - 2(7x + 3) = 14 ← distribute and simplify left side
9x - 14x - 6 = 14
- 5x - 6 = 14 ( add 6 to both sides )
- 5x = 20 ( divide both sides by - 5 )
x = - 4
Substitute x = - 4 into (1) for corresponding value of y
y = 7(- 4) + 3 = - 28 + 3 = - 25
solution is (- 4, - 25 )

Answer:
A. 12.6
Step-by-step explanation:
Sine = opposite/hypotenuse. In this case, RU is the opposite of angle N and RN (21) is the hypotenuse.
sin(37) = RU/21
RU = sin(37)*21
RU = 0.602*21
RU ≈ 12.6

Mr. Sanchez’s class sold fruit pies for $1.65 each and Mr. Kelly’s class sold bottles of fruit juice for $1.36 each. Together, the classes sold 79 items and earned $118.17 for their school.
(a) Write and solve a system of equations that model the problem. Show all your work.
(b) Which class earned more money?
(c) How much more money did that class earn?
Answer:
Step-by-step explanation:(a)
1.65p+1.36j=118.17 and p+j=79
We can say p=79-j and sub this value in first equation
1.65(79-j)+1.36j=118.17
130.35-1.65j+1.36j=118.17
-0.29=-12.18
j=42, p=79-j, p=79-42=37
(b)
1.65(37)=61.05 and 1.36(42)=57.12
Sanchez class earned more selling pies.
(c)
61.05-57.12=3.93
So Sanchez class made $3.93 more than Kelley class.

The temperature at 6.00 am was - 12 the temperature increased by 1/2 each hour for 6 hours what was the temperature in degrees Fahrenheit at noon
Answer: -9 degrees Fahrenheit
Step-by-step explanation:
Given: Temperature at 6:00 AM = -12 degrees Fahrenheit
Temperature increased each hour = [tex]\dfrac12[/tex] degrees Fahrenheit
Temperature increase in 6 hours = [tex]6\times\dfrac12=3\text{ degrees Fahrenheit}[/tex]
Temperature at noon = Temperature at 6:00 AM+Temperature increase in 6 hours
= -12+3 degrees Fahrenheit
= -9 degrees Fahrenheit
Hence, the temperature in degrees Fahrenheit at noon= -9 degrees Fahrenheit

The La Jolla tide pools are 67.5 miles from the SLMS. A map shows that 2 inches = 15 miles. What distance is SLMS from the tide pools on the map?
Answer:
25
Step-by-step explanation:
because you have to divide by 15's
Answer:
9 inches.
Step-by-step explanation:
To find out what d (distance) is, make a proportion of the values you know and d. This would be 15/67.5 = 2/d.
¹⁵/₆₇.₅ = 2/d
Variable d cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by d.
d * (¹⁵/₆₇.₅) = 2
Expand 15/67.5 by multiplying both numerator and the denominator by 10.
d * (¹⁵⁰/₆₇₅) = 2
Reduce the fraction ¹⁵⁰/₆₇₅ to lowest terms by extracting and canceling out 75.
d * (²/₉) = 2
Multiply both sides by ⁹/₂, the reciprocal of ²/₉.
d = (2 * 9)/2
Cancel out 2 and 2.
d = 9
The distance between the SLMS from the tide pools on the map is 9 inches.

Answer:
The hike is 4.5 miles
Step-by-step explanation:
We divided 3 by 2 since 3 is 2/3 done
3 ÷ 2 = 1.5
So now we know what 1/3 is; 1.5
So now we multiply 1.5 by 3
1.5 × 3 = 4.5
Thus, the hike is 4.5 miles long
