the 4th term of an ap is equal to 3 times the first term and the 7th term exceeds twice the third term by 1 find the first term and the common difference
We're given
a₄ = 3a₁
a₇ = 2a₃ + 1
Since these numbers form an arithmetic progression, we have for some fixed constant d
a₂ = a₁ + d
a₃ = a₂ + d = a₁ + 2d
a₄ = a₃ + d = a₁ + 3d
and so on, up to
a₇ = a₁ + 6d
Rewrite the given equations in terms of a₁, then solve for a₁ and d :
a₁ + 3d = 3a₁
a₁ + 6d = 2 (a₁ + 2d) + 1
2a₁ - 3d = 0
a₁ - 2d = -1
(2a₁ - 3d) - 2 (a₁ - 2d) = 0 - 2 (-1)
2a₁ - 3d - 2a₁ + 4d = 0 + 2
d = 2
a₁ + 3d = 3a₁
3 (2) = 2a₁
a₁ = 3

hope this help you!
112 ÷ 8=14, 14 is the quotient.
What is Division?The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items. Division is the reciprocal of multiplication.
The result of 112 divided by 8 is given in the number line.
When 8 is subtracted 14 times from 112 in the number line, then we get the remainder zero.
Thus, 8 is subtracted from 112, 14 times.
So, 112 divided by 8 is equal to 14 with a remainder of zero.

A small plant is 2 1/2 inches tall. How tall will it be in 3 weeks if it grows 34 inch each week? Which method will NOT give the correct number of inches? CLEAR CHECK Multiply 212×3, and then add 34. Multiply 3×34, and then add 212. Add 212+34+34+34. Multiply34×3, and then add 212.
Answer:
The method that will not give the correct number of inches is:
Multiply 2 1/2×3, and then add 34.
Step-by-step explanation:
A small plant is 2 1/2 inches tall. How tall will it be in 3 weeks if it grows 34 inch each week?
For the first week
2 1/2 inches + 34 inches
For 3 weeks
= 2 1/2 inches + 3(34) inches
= 2 1/2 inches + (34 + 34 + 34)inches
= 2 1/2 inches + 102 inches
= 104 1/2 inches
The height of the small plant after 3 weeks
= 104 1/2 inches
Which method will NOT give the correct number of inches?
The method that will not give the correct number of inches is:

there are 12 sixth graders in the debate
club, how many total members are
there?
a. 30
b. 36
c. 38
d. 40
Answer:
40
Step-by-step explanation:
I used a calculator tbh but all you have to do is multiply the number by the percentage. 30% * 40 is 12.
There are total 40 members in the middle school, option (d) is correct
What is percentage?Percentage is a measurement to find the value of a given number out of hundred.
Given that,
Percentage of the members present in 6th grade = 30%
Also, the number of the sixth grade members = 12
According to the condition,
30% = 12
1% = 12/30
Total members are 100%,
So, 100% = 40
Total number of members is 40 in the middle school.

Alexa transports flowers for Rolling Rosie's Garden Center. On her last route, she earned $450.80. If Alexa earned $0.40 for every mile, how far did she drive?
Answer:
1127 miles
Step-by-step explanation:
Since on her last route, she earned $450.80. And she earned $0.4 for every mile.
The amount earned divided by the amount earned per mile would give us the value of distance covered.
Thus,
distance covered = [tex]\frac{450.80}{0.40}[/tex]
= 1127
Thus, the distance covered by Alexa on he last route is 1127 miles.

Answer:
i think it is 44
Step-by-step explanation:
I am sorry if it is wrong
Answer:
a 44 degree angle
Step-by-step explanation:
The supplement of a 136 degree angle would be a 44 degree angle because:

A tree casts a show of 15 meters, while a 2-meter post nearby casts a shadow of 3 meters. How tall is the tree?
Answer:
10 meters tall.
Step-by-step explanation:
If the 2 meter post casts a 3 meter long shadow the ratio
is 3:2 where 3 is the shadow and 2 is the height.
3*5=15
2*5=10
Answer:
The tree is 10 meters tall.
Step-by-step explanation:
The tree's shadow is 5 times longer than the shadow of the post. So the height of the post times 5, which is 10 meters.
15/3=5
5(2)=10

An architect needs two support beams for a building. One beam has a length of 2 (square foot) 3 meters. Another has a length of 3 (square foot) 2 meters. Explain how can you find which beam is longer.
Answer:
First beam is longer
Step-by-step explanation:
Convert all units to meters
2 square foot = 0.1858 square meters=0.431 meter
First beam's length = 0.431 +3 =3.431 meters
3 square foot = 0.2787 square meters=0.528 meter
Second beam's length = 0.528 +2 = 2.528 meters
First beam is longer
