h(x)=4x-5

$\\ \sf\longmapsto h(7)$

$\\ \sf\longmapsto 4(7)-5$

$\\ \sf\longmapsto 28-5$

$\\ \sf\longmapsto 23$

What is the value of the expression? −26−(6)2 Enter your answer in the box.

alexandr1967 [171]

Is it −26−(6)^2? If so

−26−(6)^2

= -26 - 36

= - 62

If −26−(6)2 (means 6 times 2) then

= -26 - 12

= -38

1 3/4 − 4/5 = 35 twentieths − what fraction???<br><br>Plss help will give brainliest :)

let's firstly convert the mixed fractions to improper fractions and then to do away with the denominators, let's multiply both sides by the LCD of all denominators.

$\stackrel{mixed}{1\frac{3}{4}}\implies \cfrac{1\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{7}{4}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{7}{4}-\cfrac{4}{5}=\cfrac{35}{20}-\boxed{?}\implies \stackrel{\textit{multipling both sides by }\stackrel{LCD}{20}}{20\left( \cfrac{7}{4}-\cfrac{4}{5} \right)=20\left( \cfrac{35}{20}-\boxed{?} \right)} \\\\\\ 35-16=35-20\boxed{?}\implies 19=35-20\boxed{?}\implies -16=-20\boxed{?} \\\\\\ \cfrac{-16}{-20}=\boxed{?}\implies \cfrac{4}{5}=\boxed{?}$
