Answer:

5x + 2x.....combine like terms..... = 7x

5x + 2x....subbing in 1 7x - 1....subbing in 1

5(1) + 2(1) = 5 + 2 = 7 7(1) - 1 = 7 - 1 = 6

5x + 2x...subbing in 2 7x - 1...subbing in 2

5(2) + 2(2) = 10 + 4 = 14 7(2) - 1 = 14 - 1 = 13

5x + 2x...subbing in 3 7x - 1...subbing in 3

5(3) + 2(3) = 15 + 6 = 21 7(3) - 1 = 21 - 1 = 20

5x + 2x...subbing in 4 7x - 1....subbing in 4

5(4) + 2(4) = 20 + 8 = 28 7(4) - 1 = 28 - 1 = 27

5x + 2x...subbing in 5 7x - 1...subbing in 5

5(5) + 2(5) = 25 + 10 = 35 7(5) - 1 = 35 - 1 = 34

5x + 2x result values are 1 more then 7x - 1 result values

there are no values that will make the 2 expressions equal....

because 5x + 2x = 7x......and the other one is 7x - 1......so the 7x - 1 values will always be 1 number less...because ur subtracting one

Answer:

You would add 5x+2x=

7x which is one term.

Substitute 5 for X which will make 5(5)= 35 +2(5)= 10= 45

do the same for 7(5)= 35-1 = 34

so no, no value can make the two expressions equal.

in circle T with m angle STU=50 and ST=3 units, find the length of arc SU. Round to the nearest hundredth.

ICE Princess25 [194]

Answer:

arc SU ≈ 2.62 . . . units

Step-by-step explanation:

The arc length is given by ...

s = rθ

where r is the radius, and θ is the central angle in radians.

arc SU = ST·STU = 3·(50°·π/180°) = 5π/6

arc SU ≈ 2.62 . . . units

Which is equivalent

arlik [135]

Answer:

D 8√(10) ^3x

Step-by-step explanation:

We have

sqrt(10) ^ (3/4x)

We can rewrite the sqrt as ^1/2

10 ^ (1/2) ^ (3/4x)

We know that a^b^c = a^(b*c)

10 ^(1/2 *3/4x)

10 ^(3/8 x)

The numerator is the power

The denominator is the root

8√(10) ^3x

PLEASE I NEED HELP

klemol [59]

Answer: 0.25 feet

Step-by-step explanation:

Given: Jonathon has paper strips that are all equal in length.

Let x be the length of each paper strip.

Since John lines them up end to end, the length of the line of paper strips= 3 feet

Also total strips used= 12

Therefore, length of line of strips= $12x=3\ feet$

$\\\Rightarrow\ x=\frac{1}{4}\ feet\\\Rightarrow\ x= 0.25\ feet$

hence, if Jonathan is correct then the length of each strip will be 0.25 feet.
