Answer:

In the first account was invested \$3,000  at 3%

In the second account was invested \$4,000  at 5%

Step-by-step explanation:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

First account

t=1 years\\ P=\$x\\ r=0.03

substitute in the formula above

I=x(0.03*1)

I=0.03x

Second account

t=1 years\\ P=\$(7,000-x)\\ r=0.05

substitute in the formula above

I=(7,000-x)(0.05*1)

I=350-0.05x

Remember that

The interest is equal to \$290

so

Adds the interest of both accounts

0.03x+350-0.05x=\$290

0.05x-0.03x=350-290

0.02x=60

x=\$3,000

therefore

In the first account was invested \$3,000  at 3%

In the second account was invested \$7,000-\$3,000=\$4,000  at 5%

Does anybody know how to solve for “C”?.
Jobisdone [24]

Answer:

c = (b+3a)/2

Step-by-step explanation:

<u>Solve for c:</u>

  • 1/ac = 2/ab - 3/bc

<u>Multiply both sides by abc:</u>

  • abc/ac = 2abc/ab - 3abc/bc
  • b = 2c - 3a
  • b + 3a = 2c
  • 2c = b + 3a
  • c = (b + 3a)/2

SOMEONE HELP ME PLEASE!!!!!!

Answer: Choice C

The non-pencil part of the compass is placed at point G. The compass must be kept the same width that was used to form the arc shown. The idea is to draw another arc so that it starts above G (so its on the opposite side of point A) and traces out a similar path as the arc in the diagram. 

Check out the attached image to see what I mean. The new second arc is shown in red.

SRT = 20   => STR = 20.
Since STR and STU are supplementary angles, STU = 180 - STR = 180 - 20 = 160, means x = 40.
