Answer:-4
Step-by-step explanation:
-4 x -7 = 28
28-9=19
Answer:
x=-4
Step-by-step explanation:
We are given the equation:
-7x-9= 19
We want to solve for x. Therefore, we must isolate x on one side of the equation.
9 is being subtracted. The inverse of subtraction is addition. Add 9 to both sides of the equation.
-7x-9+9= 19+9
-7x= 28
x is being multiplied by -7. The inverse of multiplication is division. Divide -7 on both sides.
-7x/-7=28/-7
x= 28/-7
x= -4
Let’s check our solution. Plug -4 in for x and solve.
-7x-9=19
-7(-4)-9=19
28-9=19
19=19
This checks out, so we know our solution is correct.
The solution to the equation -7x-9=19 is x= -4

Answer:
20,500 or greater. 21499 or less.
Step-by-step explanation:
All the numbers that rounds to 21000 when rounded to nearest thousand are from 20501 to 21499.
What are rounded numbers ?We round numbers to make it easier to remember and rounding numbers to a certain place retains it's value to that place.
According to the given question Sally hopes to purchase a 2-boat trailer for around 21000 dollars.
We have to describe all the numbers which become 21000 when rounded to nearest thousand we have to observe the digit at thousands place here it is less than 5 so we'll subtract 1 to that digit and make all the digits after that zero which becomes 20000.

mZAOC is a straight angle.
mZBOC = 6x + 29°
mZAOB = 3x + 124°
Find mZBOC:
O
с
A
Answer:
47°
Step-by-step explanation:
Given that m<BOC = 6x + 29, m<AOB = 3x + 124, and m<AOC is a straight angle, therefore, m<AOC = 180°.
m<BOC +m<AOB = 180°
6x + 29 + 3x + 124 = 180
Solve for x
6x + 3x + 29 + 124 = 180
9x + 153 = 180
Subtract both sides by 153
9x = 180 - 153
9x = 27
Divide both sides by 9
x = 3
m<BOC = 6x + 29
Plug in the value of x
m<BOC = 6(3) + 29
m<BOC = 18 + 29 = 47°
how to do this question plz answer me step by step plzz
Answer:
No
Step-by-step explanation:
Diameter= 180cm
Circumference of each table
= πD
= 180π cm
Each table can fit
= 180π ÷70
= 8 guests (nearest whole number)
Since there are 18 tables, total number of guests
= 8(18)
= 144 guests
Since there are only enough tables to sit 144 guests, there are not enough tables to fit 145 guests.
Note that we cannot take the sum of the circumference for 18 tables than divide by 70 to see how many guests can fit because a guest can only be sitted on one table.
If that was done,
Total circumference
= 180π(18)
= 10179 cm (5 s.f.)
Total number of people
= 10179 ÷70
= 145 people (3 s.f.)
This is incorrect.

Answer:
From the given diagram, the measurement of ∠RQS is 106° and the measurement of ∠TQS is 74°
Step-by-step explanation:
For this problem, we are to find the measurements of ∠RQS and ∠TQS which makes up the straight line RQT. Straight lines have a measurement of 180°. So, since ∠RQS and ∠TQS make up ∠RQT, then we are goingt o set up an equation where we add ∠RQS and ∠TQS together and equal them to ∠RQT.
m∠RQS + m∠TQS = m∠RQT
Now, let's fill the information from the problem into our equation.
(11x + 7) + (8x + 2) = 180
Combine like terms on the left side of the equation.
19x + 9 = 180
Subtract 9 form both sides of the equation.
19x = 171
Divide by 19 on both sides of the equation.
x = 9
So, we know the value of x is 9. Now, let's plug in this value into each angle so we can see the measurements of each.
m∠RQS = 11(9) + 7 = 99 + 7 = 106°
m∠TQS = 8(9) + 2 = 72 + 2 = 74°

9.) The Franklin Wildcats football team was competing in the regional
championship game. The offense had the ball at the 50-yard line as they
tried to score to win the game. Their progress during each play was as
follows: gain 7, gain 2, lose 1, gain 4, lose 5, gain 27, gain 4, gain 5, gain 0,
gain 3, lose 2, lose 1, gain 1, gain 2. On what yard line did the Wildcats end? *
Answer:
96 yards
Step-by-step explanation:
This is basically just a huge addition problem that we can tackle (heh) in our heads.
If we gain yards, then we add.
If we lose yards, then we subtract.
If we started out at 50, the expression is
[tex]50 + 7 + 2 - 1 + 4 - 5 + 27 + 4 + 5 + 0 + 3 - 2 - 1 + 1 + 2[/tex].
We can use the associative property of addition to simplify this. I'm just grouping together things that look easy to do in my head.
[tex]50 + (7 + 2) - 1 + 4 - 5 + (27 + 4) + (5 + 0 + 3) (- 2 - 1) + (1 + 2)\\\\50 + 9 - 1 + 4 - 5 + (31 + 8) (-3 + 3)\\\\(50 + 9) - 1 + 4 - 5 + 39 \\\\59 - 1 + 4 - 5 + 39 \\\\58+4 + (-5+39)\\\\62+34\\\\96[/tex]

1)A fish tank has a volume of 520 in. it is emptied at a constant rate of 10 cubic inches every minute. Which equation represents the volume v,after t, time in minutes
Answer:
v=520 -10t
Step-by-step explanation:
the rate of decrease is given a variable to calculate the rate of change. v is represented by 520 - the number of minutes.
V = 520 - 10t is the representation of the decrement of the volume of the fish tank.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Given that volume of fish tank = 520 inch³
Now since volume is decreasing at a rate of 10 inche³/minute
Decrement of t minutes = 10t
So,
New volume = Original volume - decrement of t minutes
V = 520 - 10t
Hence "v = 520 - 10t is the representation of the decrement of the volume of the fish tank".
