Answer: Each pair of gloves costs $15 and each pair of hat costs $10.

Step-by-step explanation:

Let x = Cost per pair of gloves

y= Cost per hat.

As per given, we have

5x+2y=95         \ \ \ \ (i)\\4x+y=70\ \ \ \ \ (ii)

Multiply (ii) by 2 , we get

8x+2y=140\ \ \ \ (iv)

Eliminate (i) from (iv), we get

3x=45\\x=15

Put this in (ii), we get

4(15)+y=70\\60+y=70\\y=10

Hence, each pair of gloves costs $15 and each pair of hat costs $10.

Given b(x) = X+41, what is b(-10)?<br> О -10<br> боооо
ch4aika [34]
Answer: 31
step by step solution: so the function is b(x)=x+41. they want to know what the function would equal when b(-10). so b(-10) means that you would plug (-10) in for x in the function so the function would now be b(x)=(-10)+41. now all you have to do is simplify the function. b(x)=31. so the function b(-10)=x+41 equals 31. hope this helped!!! have a great day.

146+8 1/5<br> How do I solve this
cluponka [151]

Step-by-step explanation:

146 + 8 \frac{1}{5}  \\ \\   = 146 +  \frac{8 \times 5 + 1}{5}  \\  \\  = \frac{146 \times 5 + 40 + 1}{5}  \\  \\  =  \frac{730 + 41}{5}  \\  \\  =  \frac{771}{5}  \\  \\  = 154 \frac{1}{5}  \\  \\ thus \\  \\  \huge \orange{ \boxed{146 + 8 \frac{1}{5}  = 154 \frac{1}{5}}}

In a multiplicatication problem , if the first factor has 5 digits after a decimal after the decimal and second factor 4 decimal
Rudiy27
The product will have 9 digits after decimals . This is because the number of decimal points are added in multiplication.
For eg. 2.5×2.5=6.25 , 0.5×0.5=0.25 .
