Let
x-----------> cost of one hamburger
y-----------> cost of one order of fries

we know that
4x+2y=9.74--------------> equation 1
12x+y=22.77-----------> y=22.77-12x-----------> equation 2

using a graph tool---------> calculate the equations system
see the attached figure

the solution is
x=1.79
y=1.29

the cost of one hamburger is $1.79
the cost of one orders of fries is $1.29

If Tashiana buys 3 hamburgers and one order of fries
3*1.79+1.29---------> $6.66

the answer is $6.66

Make each improper fraction into a mixed number or whole number.

4) 4 1/5
5) 6 2/9
6) -6
To solve for these, just divide the most you can and then put the amount that you couldn’t divide anymore on top of the fraction. For example, 4 is the farthest I could divide and I put the 1 as a fraction of 5 as that is what was left.

Palace help me solve these two equations 14, 15

IrinaVladis [17]

14)

check the picture below... so.. is just a semi-circle and a rectangle, nothing fancy, get their area, sum them up.

15)

so... the voter turnout, is referring to, what's the percentage that voted, which year has the highest percentage... well, we simply check the percentage of the value provided from the total eligible voters, keeping in mind that, all eligible voters are the 100%

so.. for 1944

$\bf \begin{array}{ccllll}
amount&\%\\
------&----\\
86,607,000&100\\
47,976,670&x\\
\end{array}\implies \cfrac{86,607,000}{47,976,670}=\cfrac{100}{x}
\\\\\\
x=\cfrac{100\cdot 47,976,670}{86,607,000}\implies x\approx 55.39583405498$

for 1984

$\bf \begin{array}{ccllll}
amount&\%\\
-----&-----\\
167,727,000&100\\
92,659,000&x
\end{array}\implies \cfrac{167,727,000}{92,659,000}=\cfrac{100}{x}
\\\\\\
x=\cfrac{100\cdot 92,659,000}{167,727,000}\implies x\approx 55.2439380660239$
