Mathematics
1 answer:
sdas [7]2 years ago
5 0

Answer:

<u>x= 4 </u>

<u>y= -2</u>

<em>Step-by-step explanation:</em>

-3y+5x=26\\-2y-5x=-16

Solve by using the <u>Elimination Method.</u>

-5y=10\\\\\frac{-5y}{-5} =\frac{10}{-5} \\\\y=-2

Now plug y into one of the original equation.

=======================================

-2y-5x=-16

(-2*-2)-5x=-16

4-5x=-16

4-5x+5x=-16+5x

4+16=-16+5x+16

20=5x\\\\\frac{20}{5} =\frac{5x}{5} \\\\x=4

=======================================

\left \{ {{x=4} \atop {y=-2}} \right.

Pablo borrowed $50,000 to start a business. Three years later, he repaid the $50,000 along with an interest of $9,375. What was
kiruha [24]

Answer:

The annual interest rate is 6.25%

Step-by-step explanation:

We have been given that

P = $50,000

I = $9,375

t = 3 years

r = ?

The formula for simple interest is given by

I=Prt\\\\\text{Substituting the known values, we get}\\\\9375=50000(r)\cdot3\\\\r=\frac{9375}{50000\cdot3}\\\\r=0.0625\\\\r=6.25\%

Therefore, the annual interest rate is 6.25%

Help would be appreciated ( Grade 4 homework )
saul85 [17]

Answer:

 (B)  4

Step-by-step explanation:

Consider the units column. The only sum of 3 and a single digit that will end in 1 is the sum ...

  3 + 8 = 11

This tells you A = 8, so the top number is 1983, and the middle number is B78.

Considering the first two columns, we know that 83 +78 = 161, so there must be a carry of 1 into the third column. That makes it have the sum ...

  1 + 9 + B = <something ending in 4>

We know the something cannot be 04 or 24, so must be 14. Then ...

  10 + B = 14   ⇒   B = 4

__

So, the whole sum is ...

  1983 +478 = 2461

and the letter values are ...

  • A = 8
  • B = 4
  • D = 2

BARSIC [14]

3 dumplings can be made by Serenity

<em><u>Solution:</u></em>

Given that,

Serenity has 2\frac{1}{2} cups of dough to make dumplings

She uses \frac{3}{4} cup of dough for each dumpling

To find: Number of whole dumplings made

From given information,

\text{Total cups of dough } = 2\frac{1}{2} = \frac{2 \times 2+1}{2} =\frac{5}{2}

\text{Cups of dough for 1 dumpling } = \frac{3}{4}

To find the number of whole dumplings made, we can divide the total cups of dough by cups of dough for 1 dumpling

\text{Number of whole dumplings made } = \frac{\text{total cups of dough}}{\text{cups of dough for 1 dumpling}}\\\\\text{Number of whole dumplings made } = \frac{\frac{5}{2}}{\frac{3}{4}} = \frac{5}{2} \times \frac{4}{3}\\\\\text{Number of whole dumplings made } = \frac{10}{3} = 3.33 \approx 3

Thus 3 dumplings can be made
