Darren uses a family recipe to make hamburgers if he plans on using 1 1/3 cups of breadcrumbs about how many pounds of hamburger

chubhunter [2.5K]

Is this the complete question, It seems as something is missing such as how much hamburger he would use for another set amount of bread crumbs, if their is then you just have to take the same portion away from hamburger as was taken away from bread crumbs or added. Hope I helped

Please help me with my math hw

Answer:

See below for answers and explanations

Step-by-step explanation:

<u>Problem 1</u>

<u /> $\frac{3}{4}x=60\\ \\\frac{3}{4}x*4=60*4\\ \\3x=240\\\\\frac{3x}{3}=\frac{240}{3}\\ \\ x=80$

Check solution:

$\frac{3}{4}(80)\stackrel{?}{=}60\\\\\frac{3*80}{4}\stackrel{?}{=}60\\\\\frac{240}{4}\stackrel{?}{=}60\\\\60=60$

<u>Problem 2</u>

<u /> $\frac{2}{5}x=42\\ \\\frac{2}{5}x*5=42*5\\ \\2x=210\\\\\frac{2x}{2}=\frac{210}{2}\\ \\ x=105$

Check solution:

$\frac{2}{5}(105)\stackrel{?}{=}42\\\\\frac{2*105}{5}\stackrel{?}{=}42\\ \\\frac{210}{5}\stackrel{?}{=}42\\ \\42=42$

<u>Problem 3</u>

<u /> $\frac{3}{5}y=40\\ \\\frac{3}{5}y*5=40*5\\ \\3y=200\\\\\frac{3y}{3}=\frac{200}{3}\\ \\ y=\frac{200}{3}$

Check solution:

$\frac{3}{5}(\frac{200}{3})\stackrel{?}{=} 40\\ \\ \frac{3*200}{5*3}\stackrel{?}{=} 40\\ \\\frac{600}{15}\stackrel{?}{=}40\\\\40=40$

<u>Problem 4</u>

<u /> $-\frac{8}{3}m=6\\\\-\frac{8}{3}m*3=6*3\\ \\-8m=18\\\\\frac{-8m}{-8}=\frac{18}{-8}\\\\m=-\frac{18}{8}\\ \\m=-\frac{9}{4}$

Check solution:

$-\frac{8}{3}(-\frac{9}{4})\stackrel{?}{=}6\\\\\frac{-8*-9}{3*4}\stackrel{?}{=}6\\\\\frac{72}{12}\stackrel{?}{=}6\\ \\6=6$

<u>Problem 5</u>

<u /> $\frac{5}{6}x=4\\ \\\frac{5}{6}x*6=4*6\\ \\5x=24\\\\\frac{5x}{5}=\frac{24}{5}\\ \\ x=\frac{24}{5}$

Check solution:

$\frac{5}{6}(\frac{24}{5})\stackrel{?}{=}4\\ \\\frac{5*24}{6*5}\stackrel{?}{=}4\\\\\frac{24}{6}\stackrel{?}{=}4\\ \\4=4$

<u>Problem 6</u>

<u /> $\frac{5}{3}x=12\\ \\\frac{5}{3}x*3=12*3\\ \\5x=36\\\\\frac{5x}{5}=\frac{36}{5}\\ \\x=\frac{36}{5}$

Check solution:

$\frac{5}{3}(\frac{36}{5})\stackrel{?}{=}12\\\\\frac{5*36}{3*5}\stackrel{?}{=}12\\ \\\frac{36}{3}\stackrel{?}{=}12\\ \\12=12$
