If a number, x𝑥, is increased by 77, it will be equal to twice the same number decreased by 33. The correct equation for the above statement isA.7x=3(2x)7𝑥=3(2𝑥)B.x−7=2(x+3)𝑥−7=2(𝑥+3)C.x+7=2x−3𝑥+7=2𝑥−3D.7x=2x−3

If 7x = 2 then 73x = …….(a) 3 2 (b) 4 (c) 6 (d) 8

What is the solution to 6𝑥−3+7=3x−36​ +7=3?A.3223​ B.−32− 23​ C.−23− 32​ D.2332​ SUBMITarrow_backPREVIOUS

If 7272 can be written as 𝑎𝑏×𝑏𝑎a b ×b a , then find the values of 𝑎a and 𝑏b.𝑎=1,𝑏=3a=1,b=3𝑎=2,𝑏=3a=2,b=3𝑎=1,𝑏=2a=1,b=2𝑎=5,𝑏=2a=5,b=2

Choose the algebraic expression that describes the following problem.Begin with r books, double that, subtract 7, and then divide by 3. 2𝑟−732𝑟−73  2𝑟3−72𝑟3−7  𝑟−7×23𝑟−7×23  𝑟3−7×2

𝑎−24=7𝑎−24=7The first step to undo the operations in this equation is to multiply both sides by 4, which gives:𝑎4=7𝑎4=7𝑎−8=28𝑎−8=284𝑎−2=284𝑎−2=284𝑎−8=284𝑎−8=28𝑎−2=28
