Answer:
10 miles
Step-by-step explanation:
her house to school= 3+5=8 then I added two extra miles because 8+2=10
8 - 4a = -2a
7th Grade Linear Questions
Answer:
a = 4
Step-by-step explanation:
So your goal here is to get the variable on just one side, so add 4a to both sides. This cancels out the 4a on of of the sides and puts a on the other side. The new equation is 8 = -2a + 4a. Combine like terms to get 8 = 2a. Divide both sides by 2 to get a = 4. You can check your work by replacing a with 4:
8 - 4(4) = -2(4)
8 - 16 = -8
-8 = -8
Since the final result is true, (-8 does equal -8,) a = 4.

In triangle QRS, the measure of angle RSQ is 29.1*, and the measure of angle
QRS is 76*. What is the measure of angle SQR?*
Answer:
74.9 degrees
Step-by-step explanation:
All angles in a triangle must add up to 180 degrees. Add 29.1 and 76 to get 105.1, and then you can subtract that from 180 to get 74.9.

What is the quotient of 2.592\times 10^72.592×10 7 and 7.2 \times 10^47.2×10 4 expressed in scientific notation?
The quotient, expressed in scientific notation, is:
Quotient = 0.36 × 10³
Given:
(2.592 × 10⁷) / (7.2 × 10⁴)
To find the quotient of 2.592 × 10⁷ and 7.2 × 10⁴ and express it in scientific notation, we divide the coefficients and subtract the exponents.
Quotient = (2.592 × 10⁷) / (7.2 × 10⁴)
Dividing the coefficients, we get:
Quotient = 2.592 / 7.2 = 0.36
Subtracting the exponents, we get:
10⁷ - 10⁴ = 10⁽⁷⁻³⁾ = 10³
In scientific notation, the coefficient should be between 1 and 10, so we can rewrite the expression as:
Quotient = 0.36 × 10³

Answer:
slope m=--3/-2=-3/2 is required slope
Answer:
m = -3, b = -2
Step-by-step explanation:
The equation is written in the form of slope-intercept, where m = slope and b = y-intercept.
The slope is the number before x. For the equation y = -3x - 2, it's -3.
The y-intercept is the constant. For the equation y = -3x - 2, it's -2.
Hence, m = -3, and b = -2.

While parasailing. Ryan spots a dolphin on the water below. If Ryan is 228 feet above the
water and the angle of depression to the dolphin is 15, what is the horizontal distance
between Ryan and the dolphin?
Answer:
850.9 feet
Step-by-step explanation:
The horizontal distance between Ryan and the dolphin is 850.907 feet.
What is Trigonometry?One area of mathematics known as trigonometry examines the relationship between the sides and angles of a right triangle. The relationship between sides and angles is defined for 6 trigonometric functions.
We have,
Ryan is 228 feet above the water and the angle of depression to the dolphin is 15.
Using trigonometry
tan 15 = 228/ x
x= 228/ tan 15
x= 228 / 0.26794919243
x = 850.907 feet

Ben earns $10 per hour and $6 for each delivery he makes. He wants to earn more than $155 in an 8-hour workday. What is the least number of deliveries he must make to reach his goal? a) Write an inequality to model the situation. Use d to represent the number of deliveries
Answer:
the number of deliveries would be 13
And, the equation is d ≥ 12.50
Step-by-step explanation:
The inequality function is given below:
Let us assume the d be the number of deliveries
10 × 8 + 6 × d ≥ 155
80 + 6d ≥ 155
6d ≥ 155 - 80
6d ≥ 75
d ≥ 75 ÷ 6
d ≥ 12.50
hence, the number of deliveries would be 13
And, the equation is d ≥ 12.50
Teammates Pedro and Ricky got 2679 base hits last season. Pedro had 281 more hits than Ricky.
How many hits did each player have?
9514 1404 393
Answer:
Pedro: 1480Ricky: 1199Step-by-step explanation:
Let r represent the number of hits Ricky got. Then Pedro's hits were r+281 and their total was ...
r + (r +281) = 2679
2r = 2398
r = 1199
r+281 = 1480
Pedro got 1480 hits; Ricky got 1199.
_____
Additional comment
The two answers to a "sum and difference" problem are half the sum plus or minus half the difference. Here, those values are (2679/2) ± (281/2). Pedro got more hits, so his number is (2679+281)/2 and Ricky's number is (2679-281)/2, as above.
