Svetlanka [38]
<h3>Question:-</h3>
  • Combine like terms. 5y - 8 - y

<h3>Answer:-</h3>
  • here like terms are 5y,-y
  • solving like terms
  • 5y-y-8(subtracting 5y-y)
  • 4y-8

hence the combination=

\bold {4y - 8}

All the best !

Answer:

B

Step-by-step explanation:

The initial value for a function is the value of y when x=0. For function A, we can see from the table that when x = 0, we have y = 4. For function B, we plug in 0 in our equation and solve: y = 3(0) + 5, or y = 5. So, because function B has a larger value of y when x = 0, function B has the greater initial value because the initial value for Function A is 4 and the initial value for function B is 5.

160% of what number is 144
givi [52]

Step-by-step explanation:

Let the number be x

160% of x=144

160x \div 100 = 144

then we cross multiply

160x = 100 \times 144

160x = 14400

divide both sides by 160

160x \div 160 = 14400 \div 160

x = 90

therefore the number is 90

if trapezium of area 140 cm horsepower sides 10 cm apart and one of them decides is 16 cm longfind the area find the length of t
Vilka [71]

Given :

  • Area of the trapezium is 140 cm².
  • Its height is 10 cm.
  • One of the parallel side is 16 cm.

To Find :

  • The other parallel side.

Solution :

  • Let the other parallel side be x

We know that,

{ \qquad \: \pmb{ \dfrac{1}{2} \times (sum \: of \: the \: parallel \: sides) \times height} = \pmb{Area_{(trapezium)}}}

Now, Substituting the given values in the formula :

\qquad { \dashrightarrow \: { \sf{ \dfrac{1}{2} \times (16 + x)\: \times 10 \: = {140}}}}

\qquad { \dashrightarrow \: { \sf{ 5 \times (16 + x)\  \: = {140}}}}

\qquad { \dashrightarrow \: { \sf{ 80 + 5x = {140}}}}

\qquad { \dashrightarrow \: { \sf{  5x = {140 - 80}}}}

\qquad { \dashrightarrow \: { \sf{  5x = {60}}}}

\qquad { \dashrightarrow \: { \sf{  x = { \dfrac{60}{5} }}}}

\qquad { \dashrightarrow \: { \pmb{  x = { 12 }}}}

Therefore,

  • The other parallel side of the trapezium is 12 cm.
