Answer:

1) 3a + 3b

2) 3a + 4b

3) 5a +3c

4) 3a + 3b

5) 7a + 2b

6) 4a + 4c

7) 7c +4d

8) 2a + 6b

Step-by-step explanation:

1) 2a + a + 3b = 3a + 3b

2) 2a + 2b + a + 2b = 3a + 4b

3) 3a + 2c + 2a + c = 5a +3c

4) a + 2b + 2a + b = 3a + 3b

5) 4a + b + 3a + b = 7a + 2b

6) 3a + 2c + 2c + a = 4a + 4c

7) 3d + 2c + d + 5c = 7c +4d

8) a + 2b + a + 3b + b = 2a + 6b

Mick paid $2.94 in the sale tax on an item that cost $24.00 before tax. At that rate how much would he pay in sale tax for an it

s344n2d4d5 [400]

You could do this with a simple proportion.

24/2.94 = 58/x
x = 2.94 * 58/24
x = 7.11

Choose the equation that represents a line that passes through points -3,2 and 2,1

STatiana [176]

bearing in mind that standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

$\bf (\stackrel{x_1}{-3}~,~\stackrel{y_1}{2})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{1}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{1-2}{2-(-3)}\implies \cfrac{1-2}{2+3}\implies -\cfrac{1}{5} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-2=-\cfrac{1}{5}[x-(-3)]\implies y-2=-\cfrac{1}{5}(x+3)$

$\bf y-2=-\cfrac{1}{5}x-\cfrac{3}{5}\implies y=-\cfrac{1}{5}x-\cfrac{3}{5}+2\implies y=-\cfrac{1}{5}x+\cfrac{7}{5} \\\\\\ \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{5}}{5(y)=5\left( -\cfrac{1}{5}x+\cfrac{7}{5} \right)}\implies 5y=-x+7\implies \blacktriangleright x+5y=7 \blacktriangleleft$
