Answer:

Simplifying

3x + 8 = 26

Reorder the terms:

8 + 3x = 26

Solving

8 + 3x = 26

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8' to each side of the equation.

8 + -8 + 3x = 26 + -8

Combine like terms: 8 + -8 = 0

0 + 3x = 26 + -8

3x = 26 + -8

Combine like terms: 26 + -8 = 18

3x = 18

Divide each side by '3'.

x = 6

Simplifying

x = 6

$\\ \sf\longmapsto 3y=z-2x$

Take z to left

$\\ \sf\longmapsto -2x=3y-z$

Take out -

$\\ \sf\longmapsto 2x=-3y+z$

$\\ \sf\longmapsto 2x=z-3y$

$\\ \sf\longmapsto x=\dfrac{z-3y}{2}$

Work out the area of triangle give your answer to 1 decimal place

forsale [732]

<u>Given</u>:

Given that the triangle.

Let the length of the side a be 10 cm.

Let the length of the side b be 13 cm.

Let the measure of ∠C is 105°

We need to determine the area of the triangle.

<u>Area of the triangle:</u>

The area of the triangle can be determined using the formula,

$A=\frac{1}{2} a b \ sin \ c$

Substituting a = 10, b = 13 and ∠C = 105°, we get;

$A=\frac{1}{2}(10)(13) \ sin \ 105$

Simplifying, we get;

$A=\frac{1}{2}(10)(13)(0.966)$

$A=\frac{1}{2}(125.58)$

$A=62.79 \ cm^2$

Rounding off to 1 decimal place, we have;

$A=62.8 \ cm^2$

Thus, the area of the triangle is 62.8 cm²

Alison has 1.60 worth or nickels and dimes in her coin purse. She has 11more nickels than dimes. How many of each coin does she

IrinaK [193]

Answer: she had 18 nickels and 7 dimes.

Step-by-step explanation:

The worth of a dime is 10 cents. Converting to dollars, it becomes

10/100 = $0.1

The worth of a nickel is 5 cents. Converting to dollars, it becomes

5/100 = $0.05

Let x represent the number of dimes that she has in her coin purse.

Let y represent the number of nickels that she has in her coin purse.

Alison has 1.60 worth of nickels and dimes in her coin purse. This means that

0.1x + 0.05y = 1.6 - - - - - - - - - - - 1

She has 11 more nickels than dimes. It means that

y = x + 11

Substituting y = x + 11 into equation 1, it becomes

0.1x + 0.05(x + 11) = 1.6

0.1x + 0.05x + 0.55 = 1.6

0.15x = 1.05

x = 1.05/0.15

x = 7

y = x + 11 = 7 + 11

y = 18
