Answer:

35x + 114

Step-by-step explanation:

(-1/3x + 9.5) + x(3/4 + 2.5)

(-1/3x + 95/10) + x(3/4 + 25/10)

(-x/3 + 5 × 19/2 × 5) + x(3/2² + 5²/2 × 5)

(-x/3 + 19/2) + x(3/2² + 5²⁻¹/2)

(2(-x) + 3 × 19/ 3 × 2) + x(3/2² + 5/2)

(-2x + 57/3 × 2) + x(3 + 2 × 5/2²)

-2x + 57/3 × 2 + x(3 + 2 × 5/2²)

-2x + 57/3 × 2 + x(13/2²)

-2x + 57/3 × 2 + x × 13/2²

-2x + 57/3 × 2 + 13x/2²

2(-2x + 57) + 3(13x)/3 × 2²

2(-2x + 57) + 3 × 13x/3 × 2²

2(-2x + 57) + 39x/3 × 2²

(-2 × 2x + 2 × 57) + 39x/3 × 2²

(-4x + 114) + 39x/3 × 2²

-4x + 114 + 39x/3 × 2²

-4x + 39x + 114/3 × 2²

35x + 114/3 × 2²

35x + 114/3 × 4

35x + 114/12

Mr. Walker invested $65,100 in two banks, one paying 4.5% and the other 6%. If he gets $231 more on the 6% investment than that

laiz [17]

0.06x=0.045(65100-x)+231
Solve for x
X=30100
Find the amount of interest in each account
0.06(30100)=1806 first account
0.045(65100-30100)=1575 sec account
Total interest=1,806+1,575=3,381

Hayden brought 18 new trading cards. Three-fourths of the new cards are baseball cards. How many baseball cards did Hayden buy

marshall27 [118]

<span>He bought 36 baseball cards. Since 3/4 of the 48 cards are baseball cards, you need to find 75% of 48, which is 36 cards. </span>

Melanie and Michael are on the north bank of a river that is flowing east to west at a speed of 0.5 m/s. They paddle their surf

IRINA_888 [86]

Answer:

total distance travel by them to cross river is 17.3 m

Step-by-step explanation:

Assume A be the initial position of both person and B as apposite point to A

u component of velocity along SOUTH DIRECTION is 4 cos30 = 0.4330 m/s

v component of velocity along SOUTH DIRECTION is 4 cos90 = 0 m/s

total speed will be = 0.4330 + 0 = 0.4330 m/s

time taken $= \frac{width/ of/ river}{speed}$

time taken $= \frac{30}{0.4330} = 69.3 sec$

component of u in downstream direction = 4 cos120 = -0.25 m/s

component of v in downstream direction = 4 cos 0 = 0.5 m/s

total component in downstream will be -0.25 + 0.5 = 0.25

total distance travel by them to cross river is $= 0.25\times 69.3 = 17.3 m$ downstream.

The prime factorizations of 54 and 72 are shown below. Prime factorization of 54: 2, 3, 3, 3 Prime factorization of 72: 2, 2, 2,

zalisa [80]

Step-by-step explanation:

54 = 2 * 3³

72 = 2³ * 3²

To find the GCF of 54 and 72,

we find the highest common powers of their prime factors.

Highest common power for 2: 2

Highest common power for 3: 3²

Hence GCF of 54 and 72 = 2 * 3².

The answer is Option 2.
