Line A has a gradient of 6, because it is in the form y = mx + c, where m=6.Line B can be rearranged to y= 6x - 7, so the gradient is also 6.The gradient of both lines is the same, so they are...
x2 +10x-3=(x+5)2-25-3= (x+5)2 -28
If we call the unknown number 'x' we can put it in to an equation to work it out as we known 5/3 of the number is 162.5x/3 = 162then times each side of the equals symbol by 5 to get (3x/5) 5 = 162LMAnswered by Lucy M. • Maths tutor13572 Views
Treat both numbers as whole numbers - i.e 76 x 325 (remember at the end that there are still decimals!) 76 x 325 = 24,700 ( This will be explained by using the two lines by 1st method or method that the s...
We need to multiply x by powers of 10 in order to get the recurring part on its own after the decimal point, and then be able to eliminate it. 10x = 4.363636... and 1000x = 436.363636...So subtracting we ...
