1) 6r + 7 = 13 + 7r - Subtract 6r from both sides...
7 = 13 + r - Subtract 13 from both sides....
r = -6 Check answer (don't need this part)6(-6) + 7 = 13 + 7(-6)
-36 + 7 = 13 -42
-29 = -29 ( It works )
2) -14 + 6b + 7 - 2b = 1 + 5b - Combine like terms...
-7 + 4b = 1 + 5b - Add 7 to both sides....
4b = 8 + 5b - Subtract 5b from both sides....
-b = 8 - Divide both sides by -1
b = -83) 8x + 4(4x+3) = 4(6x + 4) - 4 - Distributive property
8x + 16x + 12 = 24x + 16 - 4 Combine like terms
24x + 12 = 24x + 12 - Both terms equal each other
0 = 0
Since both terms equal each other, all numbres fit.
All real numbersFred spent half of his allowance going to the movies. He washed the family car and earned 6 dollars. What is his weekly allowance if he ended with 16 dollars
Answer:
His weekly allowance is 20 dollars
Step-by-step explanation:
the full equation would be (with x equaling weekly allowance):
(x÷2)+6=16
subtract 6 from each side to get
(x÷2)=10
then multiply each side by 2
x=20

supose that the half-life of a cesium is 30 years. If there were initially 1000g of the substance,
a) give an exponential model for the situation
b) how much will remain after 200 years
After 200 years, 9.84 grams of Cesium would remain.
Let N represent the amount of substance after t years
The half-life of a cesium is 30 years., hence, this can be represented by exponential function:
[tex]N(t)=ab^t[/tex]
where a is the initial value and b is the multiplier.
There were initially 1000g of the substance
a) The exponential model for this situation is:
[tex]N(t) =1000(\frac{1}{2} )^{\frac{1}{30} t}\\\\N(t) =1000(\frac{1}{2} )^{\frac{t}{30}[/tex]
b) After 200 years (t = 200), the amount of Cesium remaining is:
[tex]N(200)=1000(\frac{1}{2} )^\frac{200}{30} \\\\N(200) = 9.84g[/tex]
Hence after 200 years, 9.84 grams of Cesium would remain

How many petals p would there be in a group of 11 flowers ? Write an equation to find the unknown. Then find the unknown.
Answer:
11
Step-by-step explanation:
The required expression that represents the total number of petals is P = n11, where n is the number of petals per flower.
Given that,
To determine how many petals p would there be in a group of 11 flowers.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Let the number of petals in the single flower is n,
The total number of petals among the 11 flowers is p,
p = n11
Thus, the required expression that represents the total number of petals is P = n11, where n is the number of petals per flower.

It's hard to see your photo but if that say m∠T than your answer would be
m∠ L.
The drawings are saying the the triangles are congruent which means all the interior angles of one triangle are congruent to the angles of the second triangle. m∠M = m∠J, m∠K = m∠E and m∠L = m∠T
Since you have two of the angles, you can also determine what m∠L and m∠T is equal to. The sum on all interior angles must be 180 degrees.
