Evaluate. 8 • [5 + (18 – 7)] ÷ 4 Please help! Im stuck.

2 answers:

8 0

8·(5+(18-7))÷4
Remember PEMDAS, Parenthesis, Exponents, Multiply, Divide, Add, Subtract
First Step: 18-7=11
New equation would be: 8·(5+11)÷4
Second Step: 11+5=16
New equation would be: 8·16÷4
Third Step: 8·16=128
New equation would be: 128÷4
Fourth Step: 128÷4=32
So the answer would be 32
Hope this helps :)

The answer is 32. This is because, first according to The Order of Operations, we do parentheses first (or other grouping symbols). So now the equation looks like this: 8(5 + 11) divided by 4. Next, we add 5 +11, which is 16, so 8(16) = 128, and 128 divided by 4 is 32. I hope this helps! If you need helps on the Order of Operation, please ask! :D

Prove that : sinA/1+cosA + 1+cosA/sinA=2cosecA

tekilochka [14]

Step-by-step explanation:

$\frac{sinA}{1+cosA} +\frac{1+cos}{sinA} =2cosec\\\\\\\frac{sin^{2}A+(1+cos)^{2} }{sinA(1+cosA)} \\\\$

$\frac{sin^{2}A+1+cos^{2}+2cos}{sinA(1+cosA)} \\\\$ and we have $sin^{2}+cos^{2} =1$

so $\frac{1+1+2cosA }{sinA(1+cosA)} \\\\$

$\frac{2+2cosA }{sinA(1+cosA)} \\\\$

$\frac{2(1+cosA)}{sinA(1+cosA)} \\\\$

$\frac{2}{sinA}$ we have $\frac{1}{sin}=cosec\\$

Finally $2cosecA$

I really hope this helps coz it took much time

I think garden center grass seed sells for eight dollars per pound Haley spent $10 on grass seeds what amount of C did he buy

Yanka [14]

If seeds are 8 per pound then you need to find the unit rate and make a proportion with how much she spent. So you can make a ratio of 1(pound) / $8 compared to x(pounds) / $10. Then, cross-multiply.
10 = 8x. Divide both sides by 8
10/ 8 = x Simplify the fraction
1 1/4 = x
So, she bought 1 1/4 pounds of seeds
