CAN SOMEONE PLEASE HELP ME!!!!!
Answer:
R=51
Step-by-step explanation:
6x-9+7x=121
add like terms:6x+7x=13x
13x-9=121
to cancel out (-9) and to isolate x, add on both sides
13x=130
divide into both sides
x=10
to solve for angle Rsubstitute 10 for x
6(10)-9
R=51
- What is the missing number for this equation? (-3) + _____ = -7
-What is the missing number for this equation ? ______ + (-23) = -11
Answer:
The first one is -4 and the second one is 12. all you will need to do is change the + to a - then do for the first one which would be -7- -3= -4 so to check it you will need to use the + to check it so it will be -3+-4=-7. and for the second one you will need to do -11- -23=12 so to check it you will need to change the - to + so it will be set up as 12+ -23=-11.

A jewelry maker is designing a crown. The crown must have at least 45 gems, using only emeralds, rubies, and diamonds. The number of rubies must be 1 less than 3 times the number of emeralds. The number of diamonds must be 4 less than the number of rubies. Which inequality could the jewelry maker use to find the fewest number of emeralds, x, that can be placed on the crown?
Answer:
Step-by-step explanation:
X is the variable and x means multiplication symbol.
X + (X x 3 - 1) + (X x 3 - 1) - 4) ≥ 45 is the answer I got.
The answer to that inequality would be
X ≥ 7 I think

From 11:15 to 11:30 AM, a whale’s elevation changed from –80 meters to –101 meters. If the whale’s elevation is changing at a constant rate, what time was the whale’s elevation –94 meters?
The time was 11:25 the whale’s elevation is 94 meters because 15 minutes elapse between 11:15 and 11:30.
What is the rate?A rate is a type of ratio that compares two values with distinct units. A rate is expressed as a fraction.
As per the given question,
From 11:15 to 11:30 AM, a whale’s elevation changed from –80 meters to –101 meters.
The whale climbed 21 feet in 15 minutes. The unit rate is 1.4 meters per minute.
There are 14 meters between -80 and -94. The whale will take 10 minutes to reach -94m at a speed of 1.4m/min. The whale began at -80 at 11:15, and 10 minutes later it is 11:25.
Thus, the time was 11:25 the whale’s elevation is 94 meters because 15 minutes elapse between 11:15 and 11:30.

Jack needs 22 pirates for every 2 pirate ships he manages.
Answer:
55, 121
Step-by-step explanation:
2*2 =4
22*2=44
but 4 is not the number we need and 4 is one less so we divide 22 by 2 and get 11 so 44+11=55
thats the first box.
The second box is 55*2+11 which is 121
55:is the first box
121 is the second empty box

4.5.1) 2x-5y=8
x=3y-1
A. Substitute the equation that is already solved for one variable into the other equation.
B. Solve for the single variable in the one-variable equation.
C. Substitute the result from the previous step into x=3y−1 and solve for the unknown variable.
D. Write the solution as an ordered pair. E. Check the solution with the equation not used in Step C.
Answer: X=29
Step-by-step explanation:
First you substitute the x's: 2(3y-1)-5y=8
Then you open parenthesis:6y-2-5y=8
Combine like terms: y-2=8
Bring the 2 to the other side: y=10
Now you substitute the y with the answer: x=30-1
Easy equation: x=29

Explain step by step how to do 10.25 x .15.
Answer:
1.5375
Step-by-step explanation:
Multiply without the decimal points, then put the decimal point in the final answer
1025 x 15 = 15375
....
10.25 has TWO decimal places
0.15 has TWO decimal places
Therefore, when you multiply with the decimal points (10.25 x 0.15), the answer should have FOUR total decimal places.
So the answer is 1.5375

Yesterday noah ran 2 1/2 miles in 3/5 hour. Emily ran 3 3/4 miles in 5/6 hour. Anna ran 3 1/2 miles in 3/4 hour how fast in miles per hour did each person run? Who ran the fastest? !!SHOW WORK!!
Answer:
Step-by-step explanation:
To calculate the speed of each one we proceed as follows:
speed=distance/time
a] Noah's speed:
distance=2.5 miles
time=3/5 hours
speed=(2 1/2)/(3/5)
=(5/2)/(3/5)
=5/2×5/3
=25/6
=4 1/6 mi/hr
Emily's speed
distance=3 3/4 miles
time=5/6 hour
thus
speed=(3 3/4)/(5/6)
=15/4)/(5/6)
=15/4×6/5
=4 1/2 mi/hr
Anna's speed:
distance=3 1/3 miles
time=3/5
speed=(3 1/3)/(3/5
=(10/3)/(3/5)
=10/3×5/3
=5 5/9 mi/hr
Anna was the fastest
