Step-by-step explanation: Doing order of operations we first do 7x1=7, then 7-4=3, then finally do 4x1/4=3/4.
Hope this helps! :)
Answer: 2.6
Step-by-step explanation:
PQ = QR (because it’s a rhombus), so
9b - 5 = 3b - 0.8
b = 0.7
And RS = PQ (again because rhombus), so RS = 9b - 5 = 1.3. Since RT is twice RS, we have
RT = 2(1.3) = 2.6.
126b + 67
Product is multiplication, so multiply 126 and b. Then 67 more, aka add
Since there are 25 students and there’s 21 at the zoo you would end up having 21 out of 25 and 21 out of 25 as a percentage is 84% because you have to look at 25 as a whole and that whole would be 100% so 84 out of 100% is equal to 21 out of 25
